hay guys iv just spend 20k on a rebuild of a RB30/26.
it seemed to run fairly clean on initial start up of engine.
have had the head off and slight tune on idol.
since this the car is miss firing n seems way too rich, fouling plugs and blowing alot of black smoke!
it is missing down low around the 2000-3500 RPM, it runs ok really low in the rev range n when you get it boosting or into the rev range it clears out.
i am wondering if anyone can help point me in the right direction, is this just the tune (i assume it has only been tuned on idol n full throttle not using the matrix mode for the microtech) or do i have a fuel or ignition problem and the computer it self?
could it have anything to do with the heat sensor in the block giving faulse readings, or injectors since they have been sittin for over a year while iv been building this engine?
there is so many things it could be if it not the tune, n i don no were to start.
this car owes me round the 50k mark n it got taken off the road a week after i bought it and has only just been finished now, a year n a half later.
you could imagine my fury as its still not right, any help would be greatly appreciated thanks
