Ok I've tried EVERYTHING..I'm pretty sure to fix this thing. It's a 95 caravan, great condition, except for it recently started idling high upon start up. Just moving it in to a parking spot I don't even hit the gas it goes straight to 50mph.

I've changed: IAC(twice), TPS, O2sensor, and PCV, all vacuum hoses and I'm at a loss as to what to do now. I've also noticed the pigtail wires that connect all three of those and one other thing that I can't figure out what it is..they were exposed to so I separated those and plugged them back in. All the mechanics I know don't know anything pass 1990, and it seems far to unsafe to drive to a shop or auto store for a code check.

Any ideas are very welcomed.

 

Welcome to DF
The high idle could be a vacuum leak, ck the hoses and ck for missing vacuum caps on the back of the plenum and the brake booster too. The other could be something holding the throttle blade open.

 

Thanks for the advise. I checked all of the above, and everything is kosher. All vacuum hoses were replaced already, but I did a second check to make sure it was all connected properly. No leaks. The brake booster is fine as well. I even removed and repositioned the TPS and IAC..again..nothing worked.
