okay....wanna guess??

EGR system is carboned up or not working.

or... the Eng. Temp Sensor

in that order, but that's only a guess from the shop idiot.

Not likely.

I changed the sparkplugs, sparkplug wires, distributor cap, rotor and a suspicious vacuum line. It still spits and sputters when I press the accelerator hard. I am going to pull the EGR valve as soon as the engine cools down. Thanks for the response, any other ideas, please dont hesitate to post, I am no mechanic. Thanks.

My water temp gauge is reading fine, so would that rule out the engine temp sensor? Or are there 2 engine temp sensors?

I removed EGR valve, sucked on hole and the diaprgm decompressed. I held it for 15 seconds, it did not appear to leak out. I think EGR is fine.

I need alot of interior parts for this truck as well. What are the names of some of the companies that sell this sort of stuff?

This indicates a lack of fuel delivery. The pressure at the throttle body will have to be checked, maybe fuel filter, injectors....

I changed the fuel filter and there is no difference. I am gonna change the fuel pump this weekend and see what happens.
