Engine ping under light throttle
Need some expert advice about this issue. It is for our G37S with 7AT.
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. |
