I have my problem posted in the general tech forum, but I think I might be having more of an electrical problem, so here goes. When I start my car for the first time during the day/morning/whenever, it starts right up and then stalls out, after 5 or 6 times starting it up and it stalling out, it will start to idle real rough for a minute or 2, then it will idle up and down, roughly from 1k to 1.5k RPMs, on occassion it will rev itself up over 1500 RPMs by itself, as if I was holding down the gas. This is the problem thus far, I dont know if the idle and the stalling are seperate problems or not. I unplugged the MAF the other day and the car started right up, but I know the MAF and both relays are good, please help!

And a list of what ive replaced so far:
Spark plugs/wires, Dist cap/rotor button, O rings on the injectors, gasket on the manifold, fuel pressure regulator diaphram, Fuel Filter, O2 sensor, both temperature sensors/sending units, MAF and both relays, and a variety of vacuum lines. Sorry for the long post.
Thanks!

 

Remove the throttle body and remove the IAC assy. Throughly clean the TB and passages and the throttle plates. I would also replace the IAC. I had a similiar problem a while back and that did the trick.

 

Sounds like a plan, I removed the IAC once and cleaned it out, as for the TB,do I just spray the fuel injection cleaner/carb spray stuff all in it? Ill replace the IAC too while im in there, thanks for the response!

 

Well Danno, looks like I owe ya a big one, cleaned out the TB real good and replaced the IAC and the car started right up. Taught it how to Idle and its running perfect now, thanks a ton!!!

 

Thats good news. Most dealer service depts now do throttle body cleaning as part of a scheduled tune up. I do mine on all the cars once a year.
