2003 6.0 ICP questions

When the ICP goes out what does it do. My truck is missing and surging and really poor gas mileage.. I already cleaned the EGR and it wasnt bad. I stopped by autozone and had them check the codes and there were any. Any idea's? Can the ICP be the problem??

Drove it today. Seems like its in the lower part of the pedal under half throttle..If I floor it, it cleans up alittle but still has half the power it use too before this all started

If the ICP sensor goes out it can do one of two things it just will not start or it goes into limp mode depending on how it went out. But either of these will generally set a code. Try unpluging the sensor (it will go into limp mode it its not there already) if the truck runs the same I would say thats it if it gets worse rule out the ICP system. Also see if you can get your dealer to run a cylinder cut out test to check the injectors. Other than that cant say much with out being there and feeling it for myself.

It all depends on which sensor the computer thinks is faulty. The ICP sensor usually kinda rought and low power. Im pretty sure you would get bad fuel milage but cant say for sure.

Didnt get a chance to disconnect it but it does run really rough and very low power and really poor gas mileage. Seems like it really runs the worst in the the mid range. If I floor it it will clean up for a bit but if i hold it for awhile it was start missing very bad. I dont think its a injector because it doesnt run bad all the time like a injector failing or gone.

Well I finally had a shop look at it. #8 injectors electrical went out and it need a major ECU updated flash. Runs like a striped ape now......The new flash even gave me better low end take off..
