Check the AC idle-up circuit - engine RPM should jump a little when the AC
compressor is engaged. Also check the Idle Air Control valve to make sure
it is not gummed up, although I would suspect that a gummed up IAC valve
would cause rough idle whether or not the AC is engaged.
(correct punctuation to reply) >> Stay informed about: My Camry runs rough in idle when I turn on the ac... why??
