I will definitely go with the AC plug. Thanks

Does it idle any better after it's fully warmed up? That would be another indication of an intake gasket issue.....they usually idle worst when they're cold, and get better as they warm up when everything expands from the heat....

It idles fine when cold. Once it comes up to temp is when it starts erratically dropping RPM with AC compressor on or off.
