Hey guys so I wanted to make sure I'm not missing anything I cleaned the crap out of the throttle body because it was pretty rough so all good there. Tomorrow I'm going to pick up an iac valve and I also have a tps in the glovebox just in case. Anyways pretty much in any circumstance the idle would get pretty high except for first initial start/idle so after that no matter if I'm in gear or neutral or park the rpms will shoot up to 1000/1100 sometimes even higher. I checked the cable and linkage on the side of the throttle body and nothing seems out of the ordinary and there's no cel. I dont think there's a vacuum leak I did plug off the hoses for the front diff actuator because I now have posi lok. I also plugged off the hoses in the engine bay for the face vents a while ago because I had a vacuum leak so only defroster vents now.

 

Plenum been fixed? They are notorious for blowing out the gaskets.....

 

Yeah about 2 years ago exactly

 

Did you reset the PCM after cleaning the TB?

 

I didn't take the tb off I just cleaned it, but if you're referring to resetting it by removing and putting the battery cables back on I did that because my cables terminals have been getting a bit corroded.

 

Probably still have a vacuum leak somewhere then.

 

Yea its suppose to be nice and warm today so gonna peak around a bit. We've been getting a lot of moisture up here in the Northeast so gotta take advantage of some nice weather.

 

By any chance, Did you remove and clean the AIS motor? ( Automatic Idle Step ) motor.

 

You mean the idle air control? I'm going to pick a new one up today the one on the back of the throttle body is what you're referring to correct?

 

With how bad the throttle body was it wont surprise me that the valve/motor is in bad shape so just better off replacing.
