it was engine pings as it was relatively loud and only occurred during acceleration from dead stop or rolling. There is no warning light or even pending code. My mechanic reviewed the fuel trims and said that it ran lean occasionally which could be the cause of the engine pings.
Engine is smooth and relatively quiet (compared to the Z) and the engine ping doesn't occur under other driving conditions. Also ran through a few tankful of fuel additives (techron & lucas) and didn't help. Quote:
