Changed both crank position sensors. Before I parked it, it was making noise from under air filter housing and it had no power. It would chug and die if I didn't let off in time. It still does it after replacing sensors. Idle is smooth, can accelerate engine in park but no power after in gear. It makes the noise either way. Low frequency noise.
