 Subject: Who knows 350 RT's?

Message:
Hear are the problems:
I replaced 318 with 360 RT, running the 318 mopar performance mod. When cold, runs fine; after warm up, idle sticks at 1100 rpms after deceleration and is killing my brakes to stop - should be at 700 rpms. Under full acceleration, it cuts out power and have to back off on the gas pedal slighty for it to power up. If I accelerate slowly, no problems, but still loss of power. Idle will sometimes fluctuate between 500 to 700 like it has a nasty cam. Sync is set to 0.
Dealer DRB test shows 02 sensor at 0 volts when cutting out under acceleration and IAC set to 80 counts when sticking at 1100 rpms after deceleration. DRB shows Fuel injectors are getting a longer pulse during cutout, but 02 shows lean condition. When main fuel line is removed and ignition is turned on, squirts 3 pulses of gas and stops, which means I am getting a primer charge, but how about prolonged fuel?
Is my IAC getting a high rpm signal from the computer because under acceleration it goes lean? No one can figure this out and I am now broke over this :-|

This is just a guess, but you could try the 5.9 R/T Mopar performance PCM. It may even out the timing and get everything working in sync.

What year is the truck? Depending on the year, some chips will have little or no variation. You could even get a Jet, Superchip, or something like that.
The 318 and the 360 have the same block, and many similar parts, but you have to factor in the different fuel/air ratios, timing, etc. If you're losing power after 2nd gear, that could be because the PCM thinks it's still controlling a 318. Maybe there is a lower fuel/air level being delivered than what is needed by the engine.

What is 318 mod.? Is this supposed to be the 318 MP high performance computer? Sure, it'll run a 360, but it won't run it well. Until you have the appropriate controller, you'll never get it ironed out. They may not have a pcm for your Dakota, but depending on what year it is, the Ram pcm may be your ticket. If not, you're gonna need one of the aforementioned add-on chips, or a custom job. Square peg...round hole....get it?
