Below 2500 rpm the engine hesitates and surges but above 2500 it runs ok. Haven't done anything yet to the truck.

No check engine light.

Note: I'm trying to find a better help site. Have tried just answer, service was terrible, tried identifix, very expensive but helpful. You all seem to be very helpful, just let me know how much I should donate/pay for each problem. Again, each problem not each question so I will have an idea of how much to pay.

Thanks,
Jim

Jim:

Don't worry about a donation. At the end, if you want to, that would be great. ANYTHING is appreciated. If you can't afford a donation, consider it free and one person just trying to help another.

Since the light is on, it becomes a guessing game. I have some questions. First, have you checked fuel pump pressure? When was the last tune up? Have you checked to see if the catalytic converter is possibly plugging?
