I have a 92 940 turbo engine shaped into a LH2.4 240. Ive been trying to fix a running rich issue ever since doing the swap, i'm about ready to light this car on fire.
Wideband reads 14 on idle but when giving gas in any gear AFRs quickly drop to 8.5, the car makes no power and starts running rough. If you don't use the gas at all the car will drive and cruse at normal AFRs
Ive tried: new 02 sensor, 3 different junkyard MAFs, new coolant temp sensor, new knock sensor, new intake hose, new timing belt, spark plugs gapped at 0.028, checked to make sure FPR isn't leaking gas.
Im really pretty sure there are no vacuum leaks (unless the intercooler is leaking, I haven't done smoke test) and that the intake hose isn't collapsing. The boost gauge reads ~7psi when attempting to accelerate. Im using the 13c turbo with boost controller all the way turned down.
Timing at idle measured with timing light reads 12 but when revving in neutral jumps around 20, not sure if that is supposed to happen...

Please I need more ideas, next thing I was gonna try is new ECUs.
