Ok, after that sound my tranny was making, i took it to a shop, but it stopped making the noise. WHile on the test drive, the guy said my motor was pinging pretty bad.
He suggested running some premium to see if that stops the pinging, and it did. What do i need to do now to make it not ping on regular 87?
The truck did have a full tuneup last summer, but end of the summer when i had to get it smogged, they had to reset the timing back to zero (guess it was retarded when they tuned it up). Didn't notice pinging difference before/after tuneup, but then again i didn't know that the noise i had was pinging at all, it thought it was mechanical.
So basically, i have limited knowledge of pinging, and almost zero knowledge about timing. Thanks for any suggestions!
