My car is 210k miles, did tune up not too long ago.

However sometimes when I have my AC on, the car will idles at very low rpm (below 800) and feels like the engine going to stall. Any input on this problem?


On freeway when I accelerate, whole car will shake. I assume this is because of engine mount?

thanks

 

any check engine lights ? codes ?

 

idle problems are almost always the IACV idle air control valve.

assuming you don't have a vacume leak or air is seeping into the system from somewhere.

So should I clean the iavc or replace it?

Where is the iavc? By the throttle body?

IAC valve is right by/under the intake, @ the drivers side front of the engine. Kinda looking like 2 inch mushroom

 

IACV is mostly like the problem if you dont have a vacuum leak or hose disconnected. The piece is mounted on the throttle body.
