ls400 erratic idle intermittent missfire very rich
Im having an erratic idle, miss fire, running rich runs great wot and still has alot of power but while driving with no throttle fluctuations just cruising it losses power until i give more throttle.
Ive replaced coils plug wires plugs caps rotors cleaned throttle body crankshaft position sensor o2 sensors maf tps iacv and coolant temp sensor im lost dude i got an ecu from the junk yard but no change it could be bad as well im pretty much out of options
