What is it now????
 

OK...so i am having a problem with my 6.0 yet again. A couple of months ago it threw a code for the FICM...I had it fixed. A week later it threw a code for the back pressyre sensor....cleaned the tube and the sensor. Worked great ....now the truck coughs sometimes when driving and when I stop at a light it dies or wants to die. No CEL came on but this is driving me crazy. It is a 04 with 65K...somkeone please help me. By the way it kinda is doing the same thing that it did a couple of years ago when the ICP Sensor went bad.....could it be again???:s:

Have you tried cleaning the EGR valve?

No I havent but that was my next thing i was going to do. Thanx.

Sounds like ICP or IPR.

Would the icp go bad again?? I just had that thing changed back in June of 09 and have only put 7 K on the truck fince then. I will have to check the IPR. Thanx
