Re: OBD-II code P1530

the idle motor is not working. when the a/c is on the idle should kick up ~100-150 rpm. your engine is going to run rough because the a/c is putting a load on the engine and the only way the engine can compensate for the extra load is by raising the idle. clean out the idle air control motor and if that doesnt work, replace it.
