Mrhavasu said:Has anyone heard of pinging problems with any years? I am not sure if this is what I hear or not. You can only hear it with the windows up and it does not seem to increase with rpms, also seems to be more pronounced on the passenger side. Also sounds like maybe tinny exhaust or leak? Any thoughts?
My '04 did this for a year before Hunt Nissan in Chattanooga 'fixed' it.
To summarize... briefly... they said it was '$hitty gas' (their words, not mine), then it was the electric fan, then they said they couldn't hear it, then they said the ignition timing was correct, then they 'fixed' it by installing a ground strap (while at the same time, retarding the ignition timing so far that the truck wouldn't fall out of a tree and the fuel mileage took a dump). So, they did acknowledge that they retarded the timing "two degrees" (no way would a 2-degree retard slow the truck down that much) and then they agreed to bump the timing back up two degrees, put two dents in my hood, and sent me on my way with a still-slow truck.
But, at least it's quiet now. A big, fat, quiet, slow pig.
