I seem to be revisiting this problem again after i though i nabbed it. Maybe it's the winter time gas mix. Question: Can old worn out fuel injectors cause part throttle detonation? My SC runs really good otherwise- no other drive ability issues. My fuel system including the pump is healthy, it's at 52 psi at idle and 62 psi under load and i don't have EGR. At first i thought it was the MAF, i put the stock one back on and it still pings.
Any suggestions?
