The tank of Shell 89 plus STP octane booster basically eliminated the ping, it pinged rarely. It came back once I went back to 87.
This morning, I changed the oil, installed the colder plugs, and THOROUGHLY cleaned the MAF sensor. I also reset the computer. The plugs had a red color to them, I'm guessing the MMO?
The ping is still there, it's a bit frusturating.
Any ideas on where I should look next. Other than the ping, the new plugs and MAF cleaning seemed to make the car run a little smoother(already ran smooth).
