I am going 55 mph. Almost coasting. Foot slightly on gas. I take foot off gas and a resonating noise occurs, then goes away. If I play the gas pedal between no gas and a tiny bit of gas I can get the noise to come and go. What could this be?
I thought it might have to do with air intake so I changed IAC valve. This did not help. I thought this because I read threads on honking or resonating iac valves.
I also thought it might be related to drivetrain, since adding or taking away power causes the noise. Could it be a pinion gear with the wrong backlash. I recently installed a new pinion seal. Maybe I tightened the lock nut to tight or not tight enough. It is a tricky setting using an old fashioned torque wrench (watching how much torque it takes to turn the shaft). Could this be possible? (unfortunately I had a bad exhaust manifold gasket at the time I did the seal and therefore did not start hearing this new noise until after I had the exh man fixed, which was several months later) |
