01 S80 T6 poor idle, running very rich

Post by rbcccc »

I have an 01 S80 T6. the car will start hard, idles violently, running extremely rich like the injectors are wide open flooding the engine. Have replaced plugs, MAF sensor, coils, cleaned the ETM, and it is still going. Should I be replacing the ETM at this point?
Any suggestions would be great.

Both banks? Bank 1=Cyl 1-3. Bank 2=Cyl4-6. Any codes being thrown? Vacuum leak would be my first suspect above all else.
