Got around to messing with the idle issue, maybe steve or someone can help me out here.
Truck idles at 1100 rpm when not moving, if your rolling in neutral or with the clutch in coming up to a red light it stays at 2k.
My vac gauge showed 16lbs (I like to see 18, but the truck has high miles and I assume this could just be normal wear?) and i have checked all vacuum connections visually, have not took propane to it yet though.
Checked throttle butterflys and the linkage. Linkage hits the non-adjustable stop and butterflys appear to be where they need to be
Unplugged iac while running, no difference. Took Iac out to clean and inspect. It was already pretty clean and everything seemed to function the way it should. Re-installed and no change. I also notice it adjusts according if i put a large load on the alternator or turn on the A/c, this makes me believe it is not the iac.
The TPS has me a little puzzled. the old one already read on a range of 15-75%, i replaced this thinking it was bad as all the other vehicles i've driven are a 0-100%, however the new one read the exact same as the old and i have read that this is normal for Chrysler vehicles. Removed TPS and turned manually with the reader hooked up, and got full 0-99 range.
Re-installed and now its idleing at 1500, i assume maybe the pcm needs to relearn the tps again.
Also should mention p1294 and p1391 popped up today, one is related to idle but this has been going on for weeks and it only popped up after i started messing with it.
