Well I thought I've been having a pinging issue for a while now...I just bought a custom chip for my car with 4 settings, base setting for the MAF, 5% leaner, 5% richer, and 15% richer. I've tried every setting and turned the timing down from 14* to 10* but it sounds the same no matter what I do. So now Im not so sure it is actually pinging, but I don't know where to start.
It's always between 2k and 3k RPM's, usually the loudest around 2800-3000. It sounds like a rattle, but almost more like a knocking kinda sound. It varies depending on load, so I might just barely hear it accellerating easy, and it gets louder the more I push on the pedal. This may just be in my head, but I think it's only coming from the drivers side of the engine...
What should I check first? Re-adjust the rockers? Could it be an exhaust leak?
On a side note, the chip seems to have fixed the popping issues I was having in the upper RPM's, and it's also running a lot cooler now too.
