When I have the AC on in my 93 L wagon, the car idles rough when I am stopped at a traffic light, if I turn the AC off the problem stops. It also

will stop if I put the car in Neutral. Is it normal for the AC to put this

type of stress on the engine, or do I have a problem that needs to

be addressed?

 

Thanks

You have a major head gasket issue!! O wait you have a 2.2 never mind!

Perfectly normal, the ac condenser take quite a bit of power to run.

I am not sure if there is an ac idle sensor or screw, I am sure someone on will know. I will grab my Service manual tonight if no knows the answerer off the top of their heads.
