April,

The TPS is basically a 'volume control', like on a radio, but it tells
the vehicle's computer the exact position of the throttle, in the form
of a variable resistance. If mileage is high, and especially if the
vehicle is from the prairies and has cruise control, a 'spot' will get
worn out on the surface of this variable resistor. If the car has a
tach, you can replicate the sputtering /jerking in first gear, if you
like. You just run the engine at the same rpm as you would on the
highway. Your description is lacking, but if the rpm test proves that
there is a 'flat spot' in the TPS, a used intake manifold is one of the
cheapest ways to get it fixed.

I used to know a guy in Russia who could get such parts without buying
the whole manifold, but he's not 'around' any more...

P.S. An analog meter across the pins of the TPS will show the problem on
the resistance scale quite well also.
