Hi all. I recently had a full overhaul done on my 1KZ engine with all genuine parts etc. Had pump serviced as well as new nozzles. Ran a dream for the first 3000 km or so. Good power after running in no smoke and very sweet sounding engine. Still runs wonderfully when driving. But I just noticed today that at a stand still when revving between 2000 to 3000 rpm there is a very strong misfire. None at idle at all. None when driving at all. Does it when engine is cold and hot but a little better when hot. In this rev range, when misfiring there is a fair amount of greyish blue smoke from the exhaust. However when driving even hard uphill etc there is no smoke at all. No smoke on idle either. No knocking sounds or anything else that is unusual.
Am at a loss why it would misfire when revved stand still bit not when under load in normal driving.
I suspect either contaminated fuel, air in fuel lines through a leak although I can see none or then a faulty injector that is not quite spraying correctly when not under load. Before I part with more cash to have this checked, any thoughts?
No error codes neither is ECU suspect as I have swapped it with a Surf one just to test and I know surf one is good.
Thanks.
