Without going into a lot more detail...
Partial/slight/intermittent rich misfire?
Timing very retarded, due to WOT switch or knock sensor?

Does the engine still make good power under this condition?
Do you get detonation / do you have a knock sensor?
Does your turbo manifold glow red after a hard run?
