is it being limited to a certain RPM or gear?

 

Could you list all the mods on truck so we can try and help find the problem

 

It is stock, and it's like it runs out of fuel. I can drive smoothly as long as I'm real lite on the pedals. It won't go past 2200 rpms.

 

Have you tried changing the fuel filter yet?

 

Never crossed my mind... just kidding. I did even though I usually do it every oil change. It had maybe 1000 miles on it and I swapped it out yesterday afternoon. Still does it though.

 

Check your actual vs demand fuel rail pressure and see if they match well, if not then you have a fuel supply issue.

 

How does one do that?

 

Edge Insight CS or CTS, Snap-on Modis, Tech 2 or similar scanner.......read through OBD port.

 

Well I don't have that yet but I'm working on it. I did however find a temp fix to the problem. When it occurs, stop turn off the truck pump the manual pump until it gets hard to pump then you are good to go for a bit more.

 

That tells me you have a fuel supply problem for sure......fix that and you should be good to go (may be filter head or lines).

Would still be smart to check your rail pressure too though.

 

Leaky filter housing possibly

 

I replaced the plastic bleeder screw with the ppe metal screw because it leaked the before but I haven't seen any leaks since.

 

The filter housing itself is probably junk. Rebuild it with a kit or replace it

 

Ok thanks

 

When I get a chance I'll trace the lines and see if there is any issues and then I'll work on getting a cts and probably a lift pump. I plan on running an economy tune for my day to day and then when I get back to NC I'll be towing heavy again.

 

Have the exact same issue on my 2004. Ever get it figured out ?

 

Are you sure it's not in limp mode? My 04.5 went into limp because of .. well I still have not figured out what caused the one time fault. But point is I was towing a 9000# trailer and no matter where I put the throttle pedal,, 67MPH (its 1600RPM I believe) is MAX it will do in limp.

FIRST read the codes and see what is stored, then clear the codes (which will clear limp) and see if it comes back.
