It pings badly. The sound in this video does not do it justice. What could it be? This only happens when the engine is warmed up. I also lose power and acceleration suffers. Flat lines at times.
-Replacing spark plugs doesn't fix it
-No sensors (oxygen, maf, tps) throwing errors
-Thermostat and cooling system works well.
I am starting to suspect carbon build in the combustion chamber. I will try and run some engine and fuel injector cleaner through it a few weeks.
had any luck with the pinging yet?
