Has anyone done this to their car? I need to adjust the idle down a hair. When the choke kicks in or even the A/C stops running, the car wants to lurch forward. I need to drop about 200 RPM'S and see how that helps. Gotr any ideas or suggestions. I need to know how to do this! Thanks!!!

check to make sure your idle screw aint screwed in to much, but its probably not even really effecting it just a little, check just to make sure,
you may want to clean the maf, it probably needs it along with the IAC, with no residue on contact electronic cleaner.

Thanks Spector, I already cleaned the maf & IAC with no change. I just read an article about throttle bodies that said don't touch any screws in the throttle body. Adjust the throttle linkage?????? What the hell???????
Anyway I now have to research to find out where the hell the adjustment screw is at. It's unnerving to be sitting at a traffic light behind someone and your car lerches forward about 6 to 8 inches until you apply more brake. It is now becoming a pain in the ***. Thanks for the advice!

Mine does that sometimes, so now I just sit in neutral at stoplights.

Had this problem with mine as well. There is an allen head scre on the underside of the TB. Make sure yours isnt backing out like mine was. |
