    also, make sure you clean the actual sensor on your TB. Sometimes the cleaning agents can leave a residue on your sensor causing it to not work properly. That will give a wrong reading to the computer causing your engine to idle weird.

    If there is one constant theme in this thread is that my Gap is off. So now im considering re-doing the Sparkplugs and re gapping them. I was looking at the sparkplug wires today and i noticed that this speed shop i took it to also removed the heat shields, could this become a problem in the future? should i get them back?

    Im also going to pull out the Idle control sensor on the TB and double check it.

    Its so strange though because in the morning it was acting up again but just now i filled up the tank before coming home and the idle was better, not smmoooth but better. Then when i turned off the A/C it got worse.

    Mine idles funky too 79,000 miles on it. I still have to do plugs and wires but cleaning the MAF seemed to help a bit.

    When I had the MAF off i opened the TB just to look inside the intake and it looks like its full of crud and gummy oil. wasnt too impressed with that.

    Alright...this is going to sound stupid but i tell it like it is. After looking at the engine today i noticed that i had left the lid a little loose. I tightened it down good to the way its supposed to be and all is better now. Ive been driving it around and its doing great. Thanks guys thanks for all of your help!
