I just had that motor problem last week...#4 cylinder wire, IAC, and carbon in the throttle body...I had all the plugs changed and fuel filter done while it was in

 

really how much did all that cost? how does it run now? thanks

 

Cost me about $500 and so far so good, been running great...problem was the truck wasn't throwin codes right away and the check engine light never came on. Mechanic had to drive it with his computers hooked up so he could get a read on it

 

i think im having the same problems, ill have to check it out

 

I got egr po401 and it was a cracked rubber egr hose between the egr pipe and DPFE

 

are you talking about the 2 rubber hoses that go to the dpfe and the metal egr tube?

i replace those when i changed the sensor
