Ok this is really buggin the crap out of me.. I have a 95 T-bird w/ the 4.6 and it pings when i get on it. i tried better gas and still does it. Also tried Octane boost and that helped a little bit but still does it.. So what can i do?? My little brother worked at a lincoln dealer a few years ago and he said that thay were pulling something under the hood that retarded the timing and when it was pulled it bumped the timing up and that solved the problem but i dont know anything about it.. If anyone can help it would be great..
