Can someone try to explain what it sounds like when the engine is pinging? I've never heard an engine ping before.
My car has been running pretty crappy. It lags alot. It sounds and feels like you're trying to accelerate from a dead stop in any gear other than 1st. Like a low rumbling sound. When the RPM is higher, I still get the low rumbling sound, except it's a little louder. Could my car possibly be knocking or pinging??
Would running very rich cause my car to lag or sound like this? My mpg is pretty bad. I only get 19-20 mpg, never had anything better than that. I get alot of carbon buildup on my exhaust.
