1997 Chevy S-10 6 cyl Four Wheel Drive Automatic

I have a 97 s-10 4by4, problem is this. Its being robbed of power, and takes a runway to get to highway speeds, I was sure it wasa tranna problem due to the fact that, it would shift hard, and seemed confused of which gear it wanted to be in, took it to a tranna place, he said it was a motoproblem, so he did new spark plugs, wires, fuel filter, oil, worked well for one day, then went back to the same struggle of getting up to speed. Could this be injectors? When it is at cruising speed it's ok, but every gear before that, I have to basically put it to the floor and get it in high rpms to consistantly gain speed. Please help

Lack of acceleration, chugging, hesitating, bogging etc. Could be caused by one of the following below.

Inspect and test all the following listed below and get back with some results

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard.

Ok well, I took it to the shop, and they basically said they didnt know what exactly, wouldnt give it a proper test drive because of mushy brakes. But, they changed the fuel filter, plugs/wires all that, ran excellent for 1 day, then same problems of choppy fuel response happend again, on way home from work just now, instead of working it through the gears with the help of feathering gas pedal, I just let it bog and rev and bog and rev (2000-2500 rpm) untill it shifted down, when it shifted down, engine light came on, and THE TRUCK RAN PERFECT! Its almost as if I forced something, is what it felt like, but then I went to the store shut truck off, went to drive home and problem re-occured, of little power and choppy revs. Its an old truck, and dont wanna pile money at it, where do you think I should put the money first? Its either cat/sensor/fuel injectors, but again, when the engine light came on after I let it do its "choppy rev" thing, when it shifted down, it ran excelletn, no problem what so ever.
