Its a pretty new issue i use to have a big cam and race it
then i made it my daily took motor out refreshed it and put a stock cam and no ping then it started and thats when i started connecting all the sensors i had unplugged like o2 knock distributor sync and even bought the rem from nick that has helped alot with finding problems that i was unaware of
i feel like some days it won’t do it till its at 200-210 temp and the hottest point of the day for me which is like 110-115 degrees
and some days does it since i get in it and start it
