Found sticking variable valve timing actuator, freed off but no different.
Scoped injectors and found opening times of 3.19ms at start up creeping up to 6ms after a short while (assuming it's trying to correct itself, otherwise cannot explain why this would happen.
Went to it yesterday, started and ran fine, would not rev up but otherwise ok - thought right , lets scope some sensors etc, stopped it and re-started and back to normal rough running
Seems very odd how a restart can either fix or worsen the fault - this happens regularly but you still cannot rev it up.
I'm beginning to think we may still have a timing issue but cannot catch it ok to scope cam / crank !
