When I accelerate it seams like it doesn't get fuel till I push the pedal a little more and at speed it does the same thing mostly at low speed any hints on what it could be ?

Check spark plug gap, Air filter, fuel filter. Sometimes the basics can solve most problems.

put the accelerator pedal down at least twice ? While cranking the engine ? key on ? what ? Your vehicle has electronic fuel injection ,not a carburator . Pushing the gas pedal doesn't do anything The only thing if pushing the gas pedal to the foor an holding it there will put it into clear flood mode , shutting off the fuel injectors .

engine light flashing means a problem needs immediate attention ----have the vehicle scanned most auto stores offer this service for free more than likely the viberation is what is setting off code

Check fuel pressure and flow. Symptoms resemble clogged filter or faulty fuel pump. Faulty fuel pumps run for a time before failing to provide proper pressure; a faulty fuel filter may function for a brief time before debris clogs it each time the engine is started...

Most likely a clutch problem. What, if anything, has changed recently? Does the clutch have 25 years of use, or has it been replaced? Is there some "free play" at the top of the clutch pedal travel? If not, you might try adjusting the clutch pedal to bell housing linkage to create such travel, just to make sure you are getting all the clutch pressure that its pressure plate can provide.
It slips in low gear because that uses the most engine force to accelerate from a stop. As you shift up, you minimize the clutch load because you wait until the engine is revved up, indicating the acceleration load between shifts is not too great. In the highest gears you are driving at highway speed using very little power from the engine to maintain that speed. If you come to a slight upgrade, not enough to require downshifting, you add extra load, again more that the worn clutch can pass through to the axle.
Do you "slip" the clutch or "ride it" when starting or driving? We minimize clutch wear by using the lowest gear that allows the truck to start without using the fuel pedal. This may be how and why you wore out your clutch.
If you can't help the problem by adjusting the external linkage, you most likely need to replace the clutch. If you are unsure, try having a competent truck mechanic evaluate it first.

You in the ball park. I would also check the idle control valve. Also, if you have not done so, check and/or change your fuel filter. GL.

Likely a clogged fuel filter or defective fuel pump. Confirm correct fuel pressure with a gauge. If the pressure is low, remove the fuel filter and check for obstruction. If it's hard to blow through it, replace it with a new filter. Then retest the fuel pressure. If pressure is still low, then it's likely that you have a defective fuel pump.

code #0406 = egr position sensor circuit high ( stuck egr valve or bad egr sensor most likely sensor )

code #2096 = downstream fuel trim system lean ( see next code )

code #0137 = O2 sensor bank 1 sensor 2 circuit low ( replace rear O2 sensor driver side )

code #2299 = brake peddle position/accelerator pedal position incompatible. ( hav you been power braking this truck? ) ( brake light was on wile accelerator was being pushed )

WELL I WOULD SAY FUEL FILTER BUT IT IS IN FUEL TANK IT IS PART OF THE FUEL PUMP ASSEMBLY.CHECK THE APP SENSOR LOCATED ON TOP OF ACCELERATOR PEDAL.MAKE SURE PEDAL IS TIGHT AND MAKE SURE THE WIRE GOING TO APP SENSOR INTACT NOT LOOSE OR DAMAGED.IF ALL IS GOOD HAVE TRUCK SCANNED FOR ANY APP SENSOR CODES.CHECK TRANSMISSION FUSE ALSO.

Similar thing happened to me, but it ended up being a clutch on its last legs....Since you have an automatic, I'd guess its your Mass Air Flow sensor or throttlr body.
