May have vacuum leaks somewhere then.

 

But me adding leaks helps? Me removing those lines creates leaks

 

Bigger leaks. Even with the IAC completely closed, the engine is getting too much air.

Also, when the PCM decides it is time to open the purge valve, it compensates for what it expects to happen, I.E. more air coming in, so, it closes the IAC some......

 

Alright so then I'm gunna try the mopar IAC's. Also then should I try sealing up all vaccuum ports and see how it runs then? Just plug every port and see what happens? I'll leave the pcv valve sucker on cuz I don't want to build up fumes in there. Any vaccuum readings I could test for? How many inches/Mercury are supposed to be present at idle?

 

I think you should have 17 to 20 inches at idle.

 

Tps was bad. But I had to replace PCM to be able to read that on the diag tool because the PCM was shot. Anyways, it runs great now. However, one issue is now I have a trans temp light on, which disables OD. The only way I can get it to shut off is by running the truck up a steep bank, like a drainage ditch, and then come back down. It must have something to do with the fluid all moving around on the valve body or something.

 

What year PCM did you get?
