Re: timing on ef/el v8
I have just come back from the performance center where they had a fellow come down with a reco'd MAF sensor. It was installed and the dyno showed the AF ratio to be correct this time and I got another 10 rwkw out of it.
So I have now learned that even though the diagnostic computer that was plugged into the engine computer showed the MAF as working correctly with no errors, it was definetly dodgy and my long running pinging problem is gone.
Never argue with an idiot. They drag you down to their level, and they beat you with experience.
