I have changed the spark plugs and the fuel pump/filter. It only jerks until I get to about 50 mph, then it runs fine.

Sounds like either a bad MAF or IAT sensor. Possibly just the connection to one of those sensors as well. The dealer scan should have been able to spot this. :-\

OMG! I have a 2001 Pontiac Sunfire too!!! Mine does that too! It will like, hiccup between 3rd and 4th gears, but then once it hits 50 MPH, it runs more smoothly. It's intermittant. I too have checked the fuel filter, the spark plugs, I've spent hundreds of dollars on diagnostic fees. I was told it might be my head gasket and shouldn't drive it, so I had it towed to the dealership. They insisted that there was nothing wrong with my car.
They claim there is "Nothing wrong" with my car. I wonder if it has to do with that recall we had. It was for some automatic switch. I haven't had mine done yet.
Have you had any problems with your radiator fluid? Mine drinks coolant like it's going out of style. I have to carry a huge jug of Dexcool in my trunk at all times....
I can't believe you have the same problem as me. I'd be so interested to see what the cause could be!!! Keep me posted!
Wait a minute... are you a Leo? Or is that just your name... because that's a freakish coincidence if you are.

sounds like a hose has cracked. that's extremely user-friendly to change hoses in case you're coherant with procedures. even with the undeniable fact which you will verify that it is the hose, and not some thing else. locate a pal it quite knows a minimum of a few thing approximately automobiles, or your dad. you ought to take it to a save, even with the undeniable fact that it may fee you 50-one hundred, in line with how lots they charge for hard artwork and no count if that's merely the hose. stop leak stuff does artwork, yet I wouldnt use it in case you have a visual leak.

it jerks because it is an automatic and it is shifting gears for you. it's called shift shock. mine does it because i accelerate fast and to change gears it must completely shut off the accelerator then use the clutch itself then switch the accelerator back on

it does this because you have a bad throttle position sensor.. this is not a transmission problem...

Because it can't get out of its own way.
