I did alot of reasearch and cummins wants 10 minimum. So i still have some power loss but im starting to notice it real bad going down the highway, and its terrible when i get to a hill i have to put it to the floor to try and keep my speed. I dont know if this is related but my fuel press guage will start going all over the place from 15 -25. Im still wondering if its not the apps because i seen alot of people complaining when those go bad it messes with the shifting, mine goes in to overdrive at 40 then past 60 or so it dont down **** but it did that before all this because once it hit overdrive it had the power to keep it moving less then half throttle. Now i cant eve pull my trailer down the highway and hope to keep up with the geo tracker in front of me.

 

Just replaced the map sensor nothing changed.

 

plumb in a different fuel pres guage yet?.....if yours is jumping all over the place spuratticly how accurate do you think it is?......and yes,I know i mispelled there but you know what i meant

 

The only time my guage gos crazy is when im not on the gas, wen im on it its fine but if im cruzing at a set speed or idleing then it goes nuts. I just hooked up my scanner and apps seems to be working fine. I think im back to a fuel issue. Has anyone had a problem with the airdog?

 

Same issue but i have a stock truck ....:/

 

I have a similar problem with a 1999 Dodge 3500 truck I need help with. It starts and runs fine but then after driving a few miles it just shuts down like you turned the switch off. I even noticed the radio display goes dead so I am sure it is electrical in nature. It will restart if you leave it in gear and allow the engine to continue turning and it takes off like a shot. I have pulled all the fuses and relays pertaining to the fuel and ignition systems and tested them all with no problems found in any of them. Anyone else ever had this problem. I also replaced the fuel filter with no improvement in the problem. It doesn't feel like it is running out of fuel because it happens instantly with no warning.
