Lately I have noticed what I think is pinging (or knocking?) at WOT. I have browsed through past articles but I couldn't determine if this was a problem that many people are having are not. I have also had on a few occasions the issue of pinging when trying to use 6th gear a too slow a speed on the highway as others have complained about.
Can anyone shed some light on what I should look into first?
I didn't see TR55 plugs in your sig......pull the stock platinums and look closely at the bottom electrode and you may see a few of the bottom platinum puc's missing. The TR55's cured mine of the problem.
