AC causes RpMs to go down?

[kyleb617]

When im Idle and have my AC on my RPMs decrease and it feells like my engine almost stalls. What could be the problem? When I drive its cool as ever but idling tends to blow out semi warm air

I actually have the same problem, except mine actually stalls almost everytime i start it with the ac or heat on. Though it seems the problem gets worse in the cold. Ive actually taken it to a shop twice to no avail, If anyone has any insight that would be great

Dirty idle air control valve?

REPLACE the IAC

9 times out of 10 cleaning it will not help....just go ahead and replace it. They aren't that expensive.
