The car is totally normal at all time with the exception of occasional engine ping during take off from dead stop or slight rolling with light throttle. Car would start fine, idle and run smoothly otherwise.

We just have to let go the throttle for a second and everything would be back to normal. Engine ping never occur under any other situation. My guess is for some reason the fuel mixture become lean and cause the ping.

I have cleaned the MAF numerous times and run through a few fuel system cleaners already. Fresh air filters and oil etc. Car is totally stock.

TIA.

Reread the problems statement... sounds like some knock at 600 RPM under load. I think this would be pretty normal for any high revving engine. You want it to go away, get a higher stall torque converter.

I wouldn't go that far, but for a guy who claims to have a doctorate, you would think he would be better with this whole written communication thing.

And these were his most useful posts. It seems like the rest of his post history is just him calling people homosexual slurs for buying an automatic.

Alright guys let's keep it on topic!

The useless replies are not helping the Op or others experiencing the same issue.

looks to be the case...

just curious if this type of engine ping for a very short duration would damage the engine?

thank you all for your inputs.
