 Subject: '93 Dakota Stalling
IP: Logged
Message:
I didn't have any luck with this in the general forum, so I will try here.
I have a '93 Dakota Ext cab V6 auto 4x4 and it has 174,000 miles on it. The problem is that sometimes after it sits for a while, like 8 hours or more, sometimes it stalls coming to a stop. The truck starts perfectly fine and drives fine until I get to that first stop. The tach drops way down and it will die. I have stopped it from dieing by putting it in neutral coming to the stop and keeping the rpms up. I try keeping it in second and drive and it always dies. Eventually, after a while, it will be fine. I drive the highway a lot, so the problem I notice with it most of the time when the dieing happens is that I get up on the highway and go about 65 and I have no Overdrive. It is running really fast. Eventually, overdrive kicks in and everything is fine after that. No dieing at all, until it sits for the day or night again. It doesn't do it everytime, but a lot. It is almost like it is in a "safe" mode or something.
Any ideas
Thanks

Brandon, as for the stalling, I would think it may be the IAC idle air control valve, if it gets dirty it will play havic with the idle, with the trans not shifting into over drive, I don't know about that. Just check the trans oil and be sure its in the SAFE zone.
Good Luck

Thanks. However, I think the two things are related. It only stalls when it will not shift into overdrive, or, it only doesn't shift into overdrive when it is having one of its stalling episodes. Yesterday, I left my house after the truck had been sitting for a few days, and I live on a country road, so I got going 55 mph and it wouldn't shift into overdrive, so I started hitting the gas on and off making the truck lerch kind of and after a few of those, it shifted into overdrive. Could something be sticking and could that cause the stalling problem?
Thanks

have you checked for any stored codes? i think it would have something to do with torque converter lockup. if the TC is staying locked up when coming to a stop it will die. it acts just like stopping a manual trans without depressing the clutch and shifting to nuetral. that would also explain the higher revs on the highway. the torque is not locking up then.

Replace the TPS (throttle position sensor) - that caused these problems for me, with no stored codes.

Thanks everyone. One last thing. Would any of the above issues only cause this to be an intermitant problem? It doesn't happen everytime I drive it. Lately, it has happened everytime I have driven it, but before this last week, it only happened every once and a while.
Thanks again

Yes, that's been my experience. I replaced the TPS due to the hot restart/stall and stall coming to idle, and lack of O/D or easy kickdown on the highway, in 2005. Last week it did it again, and now it's fine without touching anything. Check the TPS harness carefully before replacing the part; could be the contacts in the plug need cleaning and new dielectric grease.

TPS or the speed sensor drivers side of trans
this is what runs the speedo and will cause stalling
and o/d lockup problems
the tps check with digital volt meter
closed .4 to .7
should have a full 3 volt change from closed to
wide open and always return to the same low
volts
if it even temp drops lower it will stall
instantly
if .5 closed should be 3.5 or more at wide
these can also go the other way if it hangs up and
does not return to same low volts it will idle
high even load up and stall fro to much gas
IAC watch the steps with scanner around 15 to 20
warm at idle should step up as throttle is open
and return

I'm having a similar problem with my 98. It's been an ongoing
problem since last November. Cold start - beautiful no problems
- once the engine heats up it will stall out usually on the
highway - around 65-70 mpg. Made an appt w/garage. day
before I brought it in the check eng light came on. I explained
what it was doing and that I noticed it was a problem on high
heat/humid/very wet days. "Brain chip" said it was the catalytic
conv. replaced it. ran fine for about a month - interesting note
here, weather was cool and dry, as soon as the humdity and heat
kicked in check engine light back on and car doing same thing. I
waited a few days before bringing it back, because the weather
changed again and check engine light went out, just minor
problems with stalling at lights. Explained again that it was
behaving the same way as first time. They changed air control
valve. This time I barely made it home - died in the drive way.
waited 5 minutes - started right up again - Drove back to
garage, Kept it for 2 days hooked up their machines running
constantly couldn't get it die. (It was beautiful weather) Each
time the weather is rainy or very hot and humid the check
engine light comes on, and now it does the back fire thing, stalls
at the lights if the rpm gets too low, and dies between 65 and
70 on the highway. Not fun when it comes to a complete stop in
front of an 18 wheeler. I've put 1100 into this problem so far in
3months time - help!

Fuel sync in the distributor can cause this.

my 1995 3.9 dakota stalls when driving on highway or in town sometimes when I catch it and put it in neutrel it will cut back in. I can be driving doing 120kmh and it just cuts out can't figure it out put new TPS also when I shut it off it sounds like there is a huge sucking sound like vacum. Its almost always fires right back up but sometimes it takes a few minutes. After all this I noticed my cat converter was in pieces in side so I cut it off and now it backfires and blew my muffler apart is that cause no cat? or just cause the way it runs?

dddddd, just because you take the cat off shouldn't cause the thing to back fire through the exhaust, and blow the muffler off, or into pieces. I think there would be something causing it to back fire through the exhaust like late ingition timing, or a plug not firing at the right time. That would allow unburned gas to get into the exh. then ingite causing a back fire and then doing damage to your muffler.
If you have a vacuum leak, thet can also cause a few problems. check all the vacuum hoses for cracks, and dry rot replace any that are cracked, or if not sure replace, they are pretty cheap. Then check for codes, that doesn't always show anything cause some troubles won't trip a code but still cause problems.
Good Luck,
