when the car is warm, the rpm is normal until i hit the gas a little up to 2000 rpm and then it goes almost al the way down to 3500rpm, it gets real shaky then shoots right back up to 800, is it a sensor somewhere gone bad, anyone have the same problem.

 

clean the IAV

 

u guys really need to search, i just said that to someone yesterday...

 

SAME SAME, could be the IACV
