Yes I know it is misfiring but why? It sounds like coil to me, but it has only happened twice and runs as smooth as a smooth thing. It only happens as I explained in a heavy overun situation. It sounds to me like it is overfuelling, the lamda is picking it up and shutting down a bank of injectors.
After the engine has been stopped it runs fine again for hundreds of miles.
What is the 0430 by the way?
I have read that thread before, and I did the cam cover gaskets on my old 2.5!!
There no signs of oil leaks any where. My old 2.5 had the plug holes filled with oil and that didnt misfire. I would be surprised if there is oil there. Low miles and very clean!
Thanks for the quick help
