Hello. Any Advice Would Be Helpful. Lol the title pretty much sums it up. My car pings realy bad. Ive changed the wires, plugs, air fliter, fuel fliter, and I even put in 93 octance gas and it stills pings like a rainstick. I have a 1990 Pontiac Grand Am. 2.5 L approx 170K miles. Maybe thats it. Sound like a head or valve problem or what? Im lost I even bought a new egr valve not to long ago cuz I heard that will cause that. It pings mainly on black gravel roads. Any other road is hardly noticable and when the car is sitting sitting still. It dont tick it just pings
have the same problem?
