2004 6.0L Surging, Lunging, Very low RPMs.... Please Help

[04powerstroke6.0]

Hey everyone im very new to this thread this is my 1st post here. I have a 2004 6.0l and im having some trouble with it. I have a egr delete, exhaust, intake, edge evo tuner.

As im driving hot or cool outside the truck will start acting really weird, Idling very low, picking back up then surging very bad. Sitting in traffic with my foot on the brake the truck wants to take off. almost feels like it loads up with fuel and goes. Sometimes wanting to die then catches back up and idles with almost a "lope" affect. there is no codes coming up at all !!!! if anyone can help plz give me ur 2cents. its my DD

I second that! Although I didnt have all the same symptoms (wanting to take off), When I changed out my ICP it did clear up the loping!

Get a Scangauge II and monitor the IPR & ICP that will show you what is going on and check the FICM voltage too. If you want to throw parts at it replace the IPR & ICP sensors.
