ICP Injection control pressure sensor

Quick question on this. Through some forums and the like I am pointing toward this as a problem I'm having.

On these engines what happens if the wiring to this sensor is unplugged?

Also, could the outside colder temps cause this sensor to act worse? Even if the engine gets up to operating temp could this be a problem?

It appears that with a cold start and running of the machine still being cold the problems don't exist. But once it warms up but still having a cold ambient air temp, the problems show up. The warmer the outside ambient temp is the less the problems show.

Problem being like a lightning fast cut out. A jerking type sensation. If I push the go pedal it goes away. If I let off it goes away. This is not a problem with the pontentiometer. (fuel pedal)

Never heard of a IPS, you sure your not referring to the ICP? Injection control pressure sensor.

Sorry about that, yes I'm referring to the sensor you speak of. I changed the title of it. Doing too many things at once on here. Apologies.

I had a bad ICP sensor I purchased from NAPA. I noticed I had the same issue as you. When it warmed up, then I noticed it happen at the same location on the road. Try unplugging it and see if it quits. The truck will run with it unplugged as the computer creates a value in place of the value the sensor would be providing if it was plugged in. Mine did not run good unplugged, but the cutting out stopped. I went to ford and got a new sensor, no more issues.
