Fuel Issue

[eric_banks32]

I was coming home from work yesterday and I got to my exit and at the bottom theres a stop sign. When I stopped at the sign the truck acted like it wanted to die and then surged and went back and forth a couple of times, then was fine. It had only done it the one time so I kept driving trying to make it do it again and nothing. Then today it did the same thing. I also have a slight surge every now and then under moderate acceleration. Could this be bad fuel? I didn't use my normal stop when I filled up this time. Otherwise I'm gettin air or somethings going out.......

sounds more like a vac leak to me...see if anyone agrees...

Mine started to have a hesitation and stalled once, started right up, a little more hesitation. Changed the fuel filter and all has been good.

really? i dont agree. (no throttle blades to make this posible) sounds like air in your fuel system. see it on just about every cucv at one point or another.

Filter or bad fuel. A vacuum leak would be a constant problem, and could not cause surging. Change the filters, and burn out the fuel in your tank.
Cheap easy and fun! Can you say Road Trip?

might be a good idea to throw some additive in there also, maybe some diesel 911

I agree dueceman08 additive is a START, I'd try a little of each:
power service 911 (red bottle)
PS Grey bottle
Howes Lubricant - is nice you can over-treat and it claims not harmful!
---- little Grey,little red and a good lug of howes!
fuel filter, don't care what kind
if you take the hose off your fuel lift"feed"pump - blow air back into the tank.
sometimes you can get a bunch of crap on the fuel pickup "sock" whatever it's called. Take the 3 bolts out of the top cover of the injection pump take a peek in there.
take the spark plug looking thing "return line valve"? out (it's in that plate on the top of the ip) it has a rubber hose looping up and down to a steel line - and look for rubber pieces in there. could have the ip failing? hope not.
you should see a ball in there (glass) = original
steel ball <----usually the replacement and/or rebuild part installed

Stopped at the truck stop today and topped off the tank. It was just below half. Also added some Optilube XPD additive. Truck seems fine now. So hopefuly it was just bad fuel. Thanks for the input. I think I'm going to buy a filter and lift pump for cheap insurance.

i run the habbit of putting the additive in every tank. if not i every tank i would run if in every couple. can never hurt.

I run it in about every third tank. I buy it in a gallon jug and pump out what I need. It just didn't make it in this tank till I made the point to add it.
