Does it do this at a particular time, like just when cold, or only after warmed up, any time hot or cold. Also, is it only when in gear, or also when in park?

it just started all of a sudden. its kind of a random thing. When it was idling high it would continue to do it no matter what i did. i removed a little solenoid thing on the drivers side of the carbthat looked like it was pushing on the throttle. then i backed the idle speed screw all the way out. it settled down to 950-1000 rpm. then the next time i started it up it idles at 200 rpm again. i adjusted the idle so it is okay now.what would cause it to happen all of a sudden like that though? my dad thought mabe the float was sticking?

Yeah, could be. Also suspect a choke that's sticking. If you can, when it acts up again, get out, pop the hood, and tap on the carb with a screwdriver handle. Just kinda work around the fron part of the carb. This can sometimes jar a stuck float loose. If it helps, you have your answer. The whoel deal is probably in need of a good rebuild anyway.

it has been converted to a manual choke so i know thats not it. i will try what you said next time it happens. Is there any advantages or disadvantages of running the adapter/spacer to fit the edelbrock carb on my manifold?

Looking further, I hate doing this, because so many things overlap in causing the same, or similar symptoms, but the next thing I'd look at would be the EGR.
A spacer like that will move the powerband up a few hundred rpm, all else being equal, but when changing carbs, your powerband can change in such a way as to nullify any changes caused by the spacer. If you're talking about an Edelbrock AFB or AVS, you really only need a thick square-bore gasket. The gasket is made so that it seals to the curvy spread-bore intake on one side, as well as the square-bore carb on the other. When I got my first Edelbrock AFB, it had one of those gaskets in the box with the carb, but I don't know if they still do this, but even if an extra item, they're not hard to get.

wow its Jacob(street4life) again, recently i had asked about my Shelby Dakota ( and got some pretty sweet responses from both mike and gen 1(short as they where) anyways ive been looking around the internet for 360 tb, and all the stuff and learned 2 things number 1 i don't have anywhere the car knowledge i thought i had and 2, this is the place to receive knowledge, and with that being said, in non gear head terms and with having a professional install the part i buy, what is a major(semi-major) part i can buy or order whatever, that would at least bring me up to 200 HP,i wouldn't know how to install it, and to put it plainly, im 21 yrs of age with no knowledge of American v8. i had a integra gs r with a turbo kit installed(by an Asian friend) and thats about it, i just bought this Shelby Dakota which is painted lime green with roadrunner decals on the side and back,,,,,,,,,,,,,,,,im looking to make this car a monster,,,,,,first order of business, i have 300 dollars, whats a good part i can buy and have installed to begin. thanks. i saw what all did for the zac guy, i could really use help as well. if we can work together, i can show the Asian tuner crowd in my area(plentiful) why American v8 continues to dominate, also as soon as my car begins making HP gains im planing to put it on YOUTUBE and such. I have some old videos of me racing my turbo gs r(nonlegal), i would like to do that again but with my Dakota. street4life

Cam, pure and simple. The stock pre-Magnum 318 cam is tiny. If you improve the foundation with a better-breathing cam, everything else you add will build on that and can be done later. You've heard the saying, "Get to the heart of the matter." That's the cam.

where could i go to get a cam upgrade and are we talking dohc or ohv or sohc, also im on a budget so roughly how much do you think some cams would cost including installtion, by the way the car already has a cometic gasket, how much hp is that worth roughly, as far as the cam goes should i go to mopar.com and order a catalog or should i go somewhere else, also where do i get these things installed, i know this is going to sound really stupid but a dodge dealership maybe? i know when i had my integra there was little rice shacks all over the place but for american v8 i wouldnt even know where to begin. any info will help, because like i said, the anwsers to these questions help me immensly cause as you know 1989 shelby dakota isnt your everyday run of the mill car, and im trying to modify a rarly modified dodge ram engine, alll the tuners are using 360 v8 except me and select other few.

Cometic gasket? Where? Head gasket? Gaskets do not increase HP. They may help restore lost power by cutting leakage, but they don't create HP.
OHV. Summit, Jegs, Manciniracing.com.
It would help your situation a lot if you bought the book. You need to know a little more about the inner workings to make the most of what you are attempting. You'd also save a ton of money because you would then understand how to make these changes yourself, instead of paying someone else.

Best $10 you could spend.

much appreciated, and i know that if i learned how to do it my self if would be cheaper, however hypothetically speaking if i where to want to get it installed by a professional where might one go to do this? i guess ill do some digging of my own, i just havent been able to find anything thus far, and mopar has been none to helpful oddly enough. but as far as basic engine concepts ill be hitting up wikipedia and spending 10 dollars on the book perscribed. till then ill stop asking questions. peace and thanks for responding

Had the same issues with Mopar Performance when I was asking questions about transmissions some years back. They're retail-oriented. Just buy something new from us! I've seen shops on TV, but they never have anything like them in my area. You will have to case the locals and find someone who doesn't just work on Mopars, but actually knows them. For example, do they do some racing on weekends, their own shop car? Is it a Mopar? Don't mean to put you off. It's just much better for your results/satisfaction if you have more of the basics to draw from.

al right so im going to get some cams, please could some one go to this website http://www.jegs.com/p/Mopar+Performance/746961/10002/-1/10707
and tell me which ones will do the best for my 89 shelby dakota. there up top with the 318 catergory and its brand is the puprle shaft cam and lift kit, there all priced the same but work at different rpms. i was thinking because my car is a grunt worker that lower rpm would best fit its powerband, lemme know.

A week and you're ready to go? As for the cams, you only need one, and of those listed, the answer is, none of them are appropriate if you're looking at maintaining the fuel injection. The Purple Shaft line of Mopar Performance cams is not intended for computer-controlled applications. Also, the purple shaft models are flat tappet cams, you have a roller. You can switch to a flat tappet cam, but this will require longer pushrods, as used in pre-roller cam 318's, and matching flat tappets. You cannot mix roller tappet and flat tappet components. So, first question is, do you want to keep the fuel injection or rip it all out and put a carburetor on? Do you have to pass emissions testing? If so, you'll have to keep the computer-controlled fuel injection. If you go carb'd, P4452759 would be an excellent choice. If you stay with the computer and FI, use the CompCams 254HR-12 and matching springs.

well this will be my daily driver so i have to pass emissions, and the tech support at jegs said i have a speed denisty type fuel injection and any cams or preformance parts will not work out for me, and to switch to non computer carberuated, kinda like what you said. but this setup will not allow me to pass emissions, so ill go with what you said, can you post the web site that i can literally go to and purchase the compcams 254hr-12and matching springs that would be awesome( icant find it on the sites perscribed earlier), neways im really sick of people saying that this car cant be modifeid in the state its in and i really appreciate your help guy.

alright i found the website, i suppose your speaking about the chrysler 8 computer controlled w/ short snout 254hr cam, but theirs also long snout and 1.6:1 cams so i dont know which one anyways heres the website, all you gotta do is copy and paste. btw if i buy this cam setup, will i need to buy otherparts to comply with it or will i be good to get it installed and drive. i know theirs numerous things i can do but really for right now i just want to get the cam installed until i can save up for some bigger mods, like getting a mopar computer and finding a way to still have the fans run, that would be my next move. but for now the cams. http://www.compperformancegroupstores.com/store/merchant.mvc?

CCA-20-628-9
That's the part number at Summitracing.com
http://store.summitracing.com/partdetail.asp?part=CCA%2D20%2D628%2D9&autoview=sku
Actually, either short of long snout will work in your application, but since you have an electric fuel pump, the short snout is what you have now. The long snout is for a mechanical fuel pump. Again, either will fit fine in your engine. You have 1.5:1 rockers, which will put your lift numbers at .450 inches. This is CompCams OEM replacement cam because it is a bolt-in, as far as the emissions/fuel injection, etc. Now, with that much of a valve lift increase, the stock valve springs WILL NOT work. You need the proper springs.
These are the correct springs ( CompCams 901-16...a fantastic spring):
http://store.summitracing.com/partdetail.asp?autofilter=1&part=CCA%2D901%2D16&N=700+115&autoview=sku
Cheap insurance: Get new valve keeper locks. You need 8 (16 halves) single groove and 8 (16 halves of the triple groove, both sets for 3/8 valve stems. Just tell them you want intake and exhaust valve keeper LOCKS for an '89 318 with stock valves.
http://chucker54.stores.yahoo.net/valvelocks.html
The link shows hardened locks by Mopar Performance. Your stock KEEPERS are plenty strong enough, but new keeper LOCKS are a cheap, but good idea, especially with the higher pressures generated by the new cam setup. Don't forget the gasket set to button it all back up.
Want the fans to run? You can get all that at the local parts store these days. Want more? Upgrade to 1.6:1 roller rockers later, and add a 360 computer. Right now, make sure the engine is sound (compression test). If it is, you're probably okay for the cam swap. Just be VERY gentle and go slowly when swapping cams. Cam bearings are easy to ding or chip, then you have more work to do. Naturally, a new timing gear and chain should be swapped as well. NO PLASTIC GEARS! Make sure it's an all-steel set for fuel-injected systems. While you're changing springs, change the valve stem seals that are hiding beneath the springs. Never an easier time to do it, and they are also very cheap. You can get them anywhere.

Oh, and some HD pushrods are also a good idea. They're also relatively cheap.

Your stock roller rockers will work as long as the rollers are free from damage. How many miles on this thing?

the car has 128,000 miles on it give or take, apparently the car already has perfromance cam(plural) and flowmaster exhaust(true dual exhaust), i just bought a super super super small catylitc converter for it and on friday gonna get another, and the guy working at advance autoparts who i bought it from is going to help install that and a catback system and evntually make the switch over to carburated and install some headers, the enigne had been overheating because the fans wont come on, but a new heavy duty thermostat fixed that, now i need the fans to come on,THE CAR HAD BEEN COMPLETLY STRIPPED OF ANY AND EVERTHING THAT WOULD LEAD IT TO PASS EMISSIONS( before i got it), so im gonna have to tryn bribe someone to get it passed for me, and at this point carb wont make any difference on emissions that how Phucking bad i got ripped off on the car as far as it not being a daily driver unless i blow 5000 dollars roughly, anyways ill keep you updated, and as soon as i get the carb and headers(chrome) as well as make the fans run im gonna post the vehicle on cardomain.com for all dakota fans to enjoy.
