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.

SOURCE: 97 yukon 4wd. Jerks and makes noise like its

Hi amberdawn_84

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!

SOURCE: truck misses under acceleration after it's warmed up.

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

Engine cut out


Sounds like you may have fuel filter problem. you may want to check the pump and filters located in or near the fuel tank.
Go directly to the source ( Fuel Tank, Pump, Filters, Fuel Pressure Regulator and Injectors )
You may have water or grit in the fuel
Hope this helps

best advice is dont go 40mph in 5th gear... if you are going up a hill at 40mph in 5th gear i have no doubt that it is jerking, your putting too much stress on the engine. shift up to 4th or 3rd you will be fine. 5th gear is an overdrive gear. 55+mph

I am assuming your transmission is a 5speed manual. What is the tachometer reading when you experience this jerking in 5th gear? It sounds like the engine is being lugged. If you are trying to pull a hill or accelerate in 5th gear at less than 40 or 45mph, you need to downshift to a lower gear.
