rough idle and code p1211
coming home, I lost power and the truck has a rough idle. I was running a hypertech program. I can unplug the ICP sensor and the it idle fine. It gives me a p1211 code with no service light, unplug the sensor and the service light stays on. It's a 2000 7.3 with 85000 miles on it.

I would say you need to replace the ICP sensor. If you unplug it and your problem goes away, then you have found your issue.

Welcome to FTE. Unplugging the ICP will cause the SES light to come on. If it idles better with the ICP unplugged, you've either got a bad sensor, bad wiring, or a 10k type mod wired in there.
If the wiring checks out good, then replace the sensor as mentioned.

ok I pulled out the ICP out and it had oil on it. When I looked at the hold a few minutes later oil was oozing out. I ordered a new one from Riffraff diesel. I out the old one back in until the new come in. I start the truck, it wouldn't rev up or pull its self. I unpluged it and it would rev up.
