Has anyone ever experienced this noise from their SR20...it sounds like its coming from the backside of the motor. deep thumping sound...not too loud but noticable when idling in the driveway. I put my ear to the fender and it sounds like a...light thumps. Mabye 3 at a time then it stops for a couple of seconds and it does it again. Doesn't affect drivablity and recently did a compression test and all 4 cylinders checked out fine. Idle is normal. Spark plugs are fine. I do think my flex pipe has a small leak. But any ideas?
