m103 low idle and stalling when air conditioner on?

[alienman]

Hi,

My car idles "perfectly fine" at around 700rpm in gear when the a/c is off but with the a/c is turned on, the engine exhibits erratic idle and rpms jumps between 500 and around 800. I find that the engine often stalls when stuck in traffic and have to put the transmission in neutral to avoid this from happening.

I'm not sure where to start looking for a solution and hope that there is a simple one! So far, I have cleaned the ICV, replaced all vacuum hoses, changed O2 sensor, changed the ignition coil, and resoldered the OVP. Is there something else that I should be looking at that I may be overlooking? Thanks for any input you might have and have a great weekend!
