Took off the throttle body.

The inside of it looked like an old exhaust pipe. I have scene heads with less carbon deposits.

Anyways, cleaned that out. I removed what I believe to be the idle speed motor. It has torx/bolt screws on it. Looks to be a plunger. Well took that off, soaked it in a gunk solution I created haha, cleaned the inside of tb really go, shiny like a ****.

Install everything, starts up good, idles wicked again

Now, when I start it warm it revs to 2800 rpm everytime then it will rev down. Wtf. Never did this before, how can I play with this. I noticed a make shift idle screw. Never knew that was there, must be for the poor man lol Jk.

But It really annoying, any help would be great.

 

Yeah IAC (Idle Air Control) solenoids and associated passages are known to get gunked up.

 

The idle thing is possibly a vaccum leak from removing and reinstalling the part...maybe uneven tightening? I get the feeling that it's happening to my car after I removed and replaced the EGR, but I have no tach!! :/
