First, I'd like to preface this with the fact that I've been getting a constant P1221 error code and reduced engine power at random times. It's only seemed to have been getting more frequent when this sound started getting louder. I can tell that it's coming from the driver's side of my motor, so could possibly be coming from the AC compressor or alternator. Can anyone tell me if they've heard this sound before, or know what it might be? Also, could it be related to the P1221 code I keep getting? And if it's not, ideas on where the P1221 code might be coming from? It usually happens when I'm at a stop light after driving on the highway, and the idle will start to get a little rough, and progress within a 30-45 second time period to the point to where it'll come close to stalling, and sometimes actually stalling, giving me the Reduced Engine Power light.
Thanks in advance.
