Are you having any noticeable problems other than the light?

That's hard to answer, I think I am but it could also be paranoia. An online source says if a "lack" of flow in the EGR is present then I would be noticing knocking or pinging or something during accelerating or heavy loads. Well, when I accelerating I can't help but feel like I'm feeling some vibrations or stuttering or something. It's hard to describe, obviously as you can tell it doesn't seem that severe. Anyways, online source does say a lack of flow in the EGR could also contribute to overheating...last thing I want is to get stuck on the side of the road.

Bummer on your truck, especially when there's no light to at least narrow it down. How do you know it's a miss anyhow? When you say you have no light are you saying that it doesn't come on or that you your truck is old enough to not have one? I'll have to brush up on some stuff to help give you some ideas.

One question, when you say it nearly dies when you take off, are you saying it does this when you take off like a rocket ship or like a mo-ped?

I have a check engine light but it doesn't come on.

When I take off it feels like I run out of fuel and then all of a sudden it gets fuel and lurches forward. Doesnt matter taking of fast or slow have tried both ways with no different result. I have TBI and the spray seems ok, I have changed fuel filter and even put a new fuel pump in it.

The other happens at 40mph+ in 4th or 50+ in 5th gear. Basically high rpm range, the engine stutters and runs rough as hell, more of a quick sharp stutter. If I rev the engine while parkedand hold it at the same high rpms it doesnt do it.

New plugs, wires, air filter, fuel filter, fuel pump, I am lost. I checked my distributor and found a very bad and corroded pickup coil. I replaced that just cause it was in very bad shape, but thats not my problem.

I have a feeling mine may egr related or possibly tps.

I had a 93 Buick Park Avenue once that did exactly as you described on two different occasions. The first time it ended up being the throttle position sensor as you mentioned. The second time it ended up being one of the engine coils. Does your truck have coils or a distributor? If it has coils there is an easy test, of course the test isn't needed if you've already confirmed that all of your plugs are sparking...

Also, if you have a manual for your truck and a multimeter tester there might be a test for the tps to see if it's receiving the reference or signal voltage required, there might even be resistance test for the tps. You might check the price for a new one, if cheap enough it might be worthwhile just to buy a new one. Heck, you could buy it just to see if that does the trick and return it if not.

You have the ignition coils checked? I've got a 2001 F-150 4x4 and have had to replace 5 out of the 8 over the last 3 years or so. (140k miles)

I always thought that ignition coils had two posts, yours has one each?

But yea, for some reason on some vehicles they last forever and then on other vehicles, even the same model, they go bad all the time...

yup one each on mine
