Re: Harmonic Balancer Question

I have a 92 P/A and I have hear a 'rattling noise' under the car when I start driving! My brother thought it was the convector shield was loose or broke. I check it and it was fine! Could that noise be the balancer? Maybe this is why I have been replacing the cam sensor, ICM and spark plug wires with no results! Autozone told me today that the SES code was a 'MAF' or electrical problem!

Re: Harmonic Balancer Question

Get the code and post back, also thread a new thread this is too old. Yes the balancer could make the noise, take the belt of and grab the outer hub and see if is loose.

Re: 1992 PA - Harmonic Balancer Question

Does the rattle go away as the RPM's go up, or does the noise continue? Another sign of a bad balancer is the terrible noise at low RPM's. At higher RPMs I would suspect a bad belt tensioner (Which would still change with higher RPMs).

The maf may just need cleaning, but I doubt that a bad HB would cause the MAF to read wrong....odd. Separate issue from the HB if I were to guess.

Here is a tutorial on how to clean the TB, IAC, and MAF:

Re: 1992 PA - Harmonic Balancer Question

Ah, then you may just need to replae the MAF, it isn't too expensive if I remember right.

Any luck on looking into the HB rubber separation?
