This usually just happeneds when the car is cold/ hasn't been started in a couple hours or so. This morning when I was backing up I had to keep reving the car so it wouldn't die.. then it did die. When it does keep a constant solid idle when I rev it drops all the way down to 200 or less then trys to come back up. Its just really annoying to deal with.

Gonna mess with the TB screw, as requested by my tuner, but last time i checked the TB screw was as far as it could go.
Adjusted the throttle cable.. Helped a little.
Could it be in the tune, my last tune was in January and now its starting to warm up.

 

Gonna try and clean the IACV again, and replace spark plugs. See if that does anything.

 

tell me how it goes, im having the same problem as well.

 

Cleaned the IACV or well replaced it and its doing alot better, but still does it a little.
