Question about 2000 GMC Jimmy
Could be almost anything. Start by making sure the air cleaner IS the right size (poor fit can cause rough acceleration), and isn't loaded up with crud which tends to "choke out" the engine when under heavy load..

SOURCE: poor acceleration
Two common reasons for your symptoms are clogged CAT and clogged fuel filter. Take a look the trucks service history. If its been more then 2 or 3 years, it may be time.

My 97 yukon did the same thing (I believe). The valve body in the transmisson wears out (design problem) and causes the transmission to shift really hard. My repair was about $500 (nondealer).
LOVE MY YUKON!

that is a tricky one you have almost replaced everything. that is fuel injected if you dont have the right fuel pressure when you step on the gas it will fall on its face you need to take a fuel pressure reading and also it could be as simple as the fuel filter which is often over looked it could be cloged restricting the flow. also check the MAP sensor
