What is pinging when changing the timing in your car? I went to the track and a guy said he would help me bump it a lil, not sure exactly how much it was (should find out) but I want to know what the symptoms...Thanks

Pinging is when you've advanced it too far. You'll physically hear the pinging when its happening. Don't let it ping for too long. :nono:

It'll sound like rocks in a coffee can. Listen to mid 80s Oldmobiles and Cadillacs as they go by, they usually have pinging. It's also called detonation and you don't hear it until it's already bad.
