94 Q45a power problem?

Question

I have a 94 Infinity Q45a that runs great until you turn the AC on, then the idle drops down considerably and is rough. When driving and have to stop fast it dies. Any idea what this might be? Thanks!

Answer 1

It is called the AAC IAC valve yours is not working either the connectors two of them have corrosion or the valve itself is not working. The real long name is "air conditioning air control valve and Idle air control valve" made as one part and your car will idle much better after a Nissan Infinity tech replaces it and relearns the computer to idle at the right speed
