Hey Gents,

My '03 f-150 is telling me that bank 2 is running too rich.

It just rolled 200000 Kms and I just had the head gasket done.

I haven't been under the hood yet but the truck is idling fine and is burning A LOT of fuel. (even more than normal)

Since it is only happening in 1 bank I have ruled out any problem with the MAF. A few guys have suggested a vacuum leak, but I think that a vacuum leak would probably cause the motor to run lean. correct me if I'm wrong.

So far my best guess is a bad injector.

Has anyone tested injectors on these babys before?

- How long is the rail supposed to stay pressurized after the motor shuts off?
- How much pressure is supposed to be in there?

Anybody else have any other ideas?
