Are you hearing a rattle from the engine? I has this problem about a month ago. It was pinging real bad. sounded like the rocker arms were beating the hell out of the top of the valves. that was with a 91 tune with 93 oct fuel. i went back to the 87 tune and it was way better. i havent installed the 91 tune back in it yet. but i think it was just bad fuel since that was the 1st time it did that.
