Help please , stock 2002 Z28 , Pinging badly ! My friend purchased a stock 2002 camaro Z28 manual
with 70K Miles .
He noticed the car is pinging badly above 3000 RPM , the knock retard is around 3.5 Degree , the pinging noise is very noticiable .
Any advice how to solve the problem or what to check .
Thanks
