Hi there I've got a 2006 F350 Amarillo with 6.0L I'm having motor problems I drive pretty hard most of the time. Its got a 4" straight pip, valient ram air intake, and running a bullydog power pup. Ok truck starts fine idels fine but when rpm gets to 2000 it misses until normal operating temp then runs better but still feels like not getting fuel and misses . Once in a wile it will completey shut down and run on 2 or 4 cylendres and blow white smoke ( big cloud ) it's not Water it raw deisal.it through me a u2210 code I changed icp sencer seemed to work for 10 min or so then went right back to the way it was. Brought it to a friend of mine who's got a deisal shop hooked it up to his computer and everything looks good. He said It might be PCM so I got one from a recker that mached s# put it In and same thing misses and got no power If any one has experienced or may know what's going on I'm lost. Thank you. O and when high idel is on it surges between 1500 and 2700 rpm

 

Have you checked ficm voltage?

 

Sorry yes I have. I had it on a snap on scan tool and everything checked out good

 

Try pulling the ficm of and testing it manually. Sometimes the scan tools can lie..... If it test out good then start looking at injectors... How many miles or kilometers on the truck?

There is 137 miles on the truck and I got a new code is p2290 low injector pressure could it be my IPR??

 

Whats you ipr pressures doing? Can your scanner display those codes? and do you mean 137K?

 

221000 k my IPR is at 30 % at idle on my scan gauge 2

 

Do you know if the truck has ever had the stc fitting update done on the hpop?

 

I only had the truck do 6 months so I have no idea

 

I got an up date for u guys .. Spent 2 days playing with my truck and found 2 injectors on the way out #6and #8 .. Put new ones from ford in went for a ride and got a p2210?? I think it's a nox sensor low voltage.. And truck still runs like crap... Feels like a revlimiter on a gas job?? Any ideas
