I can't believe there is no more replays on this, I have heard of this problem but last two days I did some reading and this seems to be serious problem for GM , I can't believe GM have not come forward to address this, chevy have always have the best v8 , WHAT HAPPENED !? GM forgot how to make a v8 engines ?almost seems like a liberals are in charge at GM and purposely design faulty v8 to scare people not to purchase them, if we don't want to go electric they will force us ....just saying , probably am wrong but,... I have a problem with chevy forgot how to make a good V8, what's behind this ??
