My Truck stumbles past 1/4 throttle it feels like i hit a wall any time i go past 1/4 throttle i just replaced the lift pump last night after this started happening i also bleed the injectors a couple times any more ideas on wat could be wrong, this started happening yesterday morning

 

Change the fuel filter if you haven't already. It sounds like a restriction problem.

 

i just changed it this past saturday

 

Hmmmm. It starts up OK, you don't have to bleed it?

 

ya it always started fine i just started over and bleed the injectors the fuel filter and the line from the lift pump and it seems to run alright i primed the lift pump for awhile to

 

I would think its the fuel filter too. You might pull the filter off and dump it out to see if its plugged full of crap. You might have gotten some bad fuel. Otherwise I'd look into the lift pump.

Is there something internal in the IP that could be causing the stumble? It seems like some have had the same problem, and something was amiss inside.
