I am hearing something that sounds like "pinging" coming from my car above 4500-5000 rpm in third and fourth gear.
Don't really hear it at lesser RPM.
Haven't really tried (or noticed) the sound in first or second gear.
Mods are as follows:
2.76, TR-6 plugs, CAI, Catted X, Stingers and KMS Tune
I have tried filling up with 100 octane, and also put Bob's "conservative" tune in the car. Neither of which has resolved the issue.
Car ran great up until about two weeks ago. I thought it could be bad gas, so I filled up with 8 gallons of 100.
Ran that tank down, and filled up with another 12.7 gallons of 100 tonight.
I always use Shell, Amoco or Mobil 93.
Anybody have any ideas on what could be the problem?
Thanks
