Anyone have a experience with this sound or something similar? Pulled off one coil pack connector at a time. Didn't hear any difference in noise or frequency. It's more noticeable when warm at idle or light throttle. Goes away with medium to WOT.
When given throttle the noise comes back when quickly letting off.
Not sure if related but car idles low when put in gear and hesitates when given heavy throttle. I noticed when I unplugged cyl 1 coil pack, there was no difference in rpm while running. May have a bad coil pack not positive yet though. Going to do compression check and hook up oil pressure gauge this weekend.
Car is 4.6, 45,000 miles, automatic. Only mod is CAI.
