bizarre trouble codes?

[kevinator]

My 2004 f350 is sounding like it is missing at idle and idles erratically and sometimes stalls.Check engine light is on and the codes are u2205 and u2210, any ideas?

to the org! Sorry you are having trouble, but here's a bump for ya so the techs will see this and reply.

U codes are network codes.....as in module to module communication....

your miss sounds like a possible under valve cover harness though..or possibly a bad injector....

Just got my truck back from the dealership. The tech found the icp reading to be erratic. Performed icp and ipr test. Performed fuel pressure test. Removed icp sensor connector and found icp sensor leaking oil into connector end. He replaced icp sensor,and replaced connector end. Truck is back running good,just in time before the good ol Canadian winter sets in. Thanks for the bump Evil eye.Thanks for the quick response Marc. Your friend north of the border.
