Pinging at WOT..Plugs bad?
Getting pinging at WOT, and I have searched and found that Plugs can sometimes be the cause. I have tr55's in there now, they have been in since I bought the car. What is a good plug for my mods and what should i gap them. I have seen people gap them all the way from .38 - .60. why such a range?

I've been having the same problem lately. The car starts to ping right in between shift points. I know this is slowing me down since the knock sensors are picking this up and retarding the crap out of the timing. I've been running only 93 octane and I can't get anything higher locally. HELP!

I dont thimk plugs are where you should start looking.But if you change them and the problem goes away thats great.Do you have a way of checking with a scanner for Knock retard while driving?Have your temps been above normal?Check out GM service bulletins on detonation troubleshooting.That will give you a step by step approach to finding your problem.Good luck
