Default Detonation fixed!

I have had pretty bad ping at high rpm wot operation. I thought that since the maf was descreened it was leaning the mixture at WOT or something. So I have held off until I could afford a tune for it.

Then I got the bright idea to clean the MAF with some electrical contact cleaner from radio shack. I used a q-tip to carefully clean the sensors which were black. Now, no more detonation, even with WOT runs third to fifth gear yesterday at almost 90*. If I would try that before, it would sound like popcorn.

Interesting. Did you have a CEL on?

Since it's gotten hot, mine is pinging badly.

The MAF is one of the first things to check if you have detonation. If it's dirty it is showing less air to the computer than is actually coming in, which makes it run lean.
