The truck starts up good then it starts to have what sounds like a miss and idles real rough and runs rough under 2k rpm (cold or hot). Any time I let off to shift it runs rough. Have had a Po122 that came and then went off the next morning. Fuel pressure stays around 16-17.  

 

Any help would be greatly appreciated. 

 

02 3500 HO, 210k, 75hp stick( new from DAP), Fass 150, Diablo Power Puck. Have guages.

Here's the article: 

I would start there with the apps and do some testing. If all of that comes back okay, we can add in some more suggestions.

 

Thanks

I thought the APPS went with a dead pedal issue?

Talk to Fred at DAP, looks like I had air in my injector line. I am still going to do the Apps test this weekend.
