1/4 Throttle Tantrums
Not sure why but the truck at 1/4 throttle seems to miss and kind of fall on it's face. Smack it to the boards and it clears up. Anybody have a clue? Fuel delivery? Air leak?

start threadjack/ You went from having two 4x4 trucks to having 2 2wd trucks in a month. .... what trans in the D350? Did they even make a 93 crew cab?

I'd try checking fuel pressure and new fuel filter.

Well I swapped out the filter and got a bit more throttle response but the higher rpm stutter is still there. If I manually shift the trans and let is wind up in 1st and 2nd is when I notice it.

Thanks guys, found the culprit. The feed line on the pump was just loose enough to suck a bit of air. I tightened it back up and it runs like new.

Ok, so I guess the truck made a liar out of me. It's still doing it, not as bad, but still. What else could it be? It doesn't smoke any color when it does it, it just stumbles until either I let off of it or get on it a bit more. I notice it really if I leave it in 2nd gear and the rpm's climb up a little ways.

Well, after several months of being apart and put back together only to come apart again, I'm driving the truck. But, much to my dismay I still have this problem. I have so far replaced every part (with the exception of the LP and injector lines) of the fuel system. I've put a new line from the tank to the LP, line to the IP, new PODS and sealing washers and return line washers, along with a return line, I even changed to a new sending unit in the tank (fuel gauge works now). Still I can't figure this out.

It wouldnt be injector lines, they would be wet if they were leaking...
Checked the fuel heater gasket?
Have you put a clear plastic line on the supply side to the lift pump yet? <----thats one of the most useful tools...
Where is your timing at?
