Wierd idle...help

Post by SPUMONI_RT »

After the car is warmed a little, were the idle drops after start up. I'm not sure of the exact rpm but I think it is around 700rpm maybe it will run at a low idle and jump up for a second every few seconds. It isn't random it has a sequence, it is only when idleing once warm.

Where is the IAC and how do I clean it? Should I use air flow sensor cleaner or whatever it's called?
Thanks

Has your check engine light came up? Id check for possible codes and than clear the old and see which ones come back.

Id say clean the MAF, IAC and Throttle Body its worth a shot and pretty cheap.

You can do a search for most of this stuff, Im pretty sure its all been answered before.

Good Luck!
