B23F, naturally aspirated. Runs rough at idle, engine surges side to side abnormally in engine compartment and shakes the car with it, and really lacks power. Lacks so much power that the load on my alternator from turning on my electric fan will make it stumble... I've checked TPS, air mass meter is ok, and no vacuum leaks. I'm suspecting the O2 sensor because it was dropped in a pan of oil the other day... but will a bad O2 sensor cause this much trouble? Unplugging it is a good way to test, right? I was wondering about the idle air motor, but now i don't think that's it. I'll check spark and fuel too, but i checked those so recently i don't think that's the problem. Thanks!
