My car recently started pinging, this only happens when Im at the 1/4 mile or really really flooring it. Basically it happens at WOT in 3rd Gear at high RPMs. I read in another forum (http://www.corral.net/forums/showthread.php?s=&threadid=84438&highlight=Holy+Grail) that using AWSF 22C Motorcraft Spark Plugs would solve my problem, but according to a salesman at a shop he says late model mustangs should only use platinum plugs. I dont wanna do anything that'll mess up my car.... Anyone have any suggestions regarding if its ok or not to use those spark plugs or to what my problem could be?
TIA
