540i problem.

First post.

Tried to search.....

I have a 94 E34 540. It ran fine going to work, but when I started it to go home it did not!
Real loopy idle and hardly runs at all.
Pulled a plug, and it is black with sot, so something's up with fuel delivery.
Makes me think MAF.
Any ideas?

Well, it's not the MAF or the ICV.
Has anyone ever had the intake air temp sensor go bad?
Read somewhere that it will go rich if it fails.
And it is rich!
Luckily I have another motor, so I'll try switching it out tomorrow.
I also ordered two new lambda sensors, just in case.

Sounds like ICV... No easy way to get to it on V8.

The ICV is the easiest parts to get to on the M60. It is located right on top of the engine on the radiator side near the end of the intake.
