I have a 95 TI that my wife says pings, I had her switch to 93 and it helped but on hot days on a grade it still pinks a tad. According to her. It may have a knock sensor issue too, I have yet to read the codes out. I also wonder if carbon has built up to the point that it is pinging, the CR is so high to begin with I can see how this could happen. Next step is to add some xylene, I do this on my blown Chevy to keep it out of detonation.
