throwing parts at is a waste of money. misfire can be one of 3 things. cam sensor or crank sensor or fuel injector. other things can can be a air leak too much air in the intake or leak in vacuum line. can also be the timing is out.. this can be the adjuster weak.
Ok that to me sounds like you need to clean the throttle body it easy buy carburetor clean just srap a little inside the throttle body n clean it that will help you the problem is the trottle body gets dirty sticky and won't idle good n stall remember don't put to much. Just a few spats inside the when you put the hose back it might take a few minutes to start because of the amount also don't accelerat it to high when it start good luck
throttle position switch sounds like getting false readings to computer, incorrect volts or excessive play from the throttle plate or sensor causes this,has to be one or the other,also check for any intake leaks from the filter to the throttle body,good luck,Gary
I'd bring it back to the shop that put in the throttle body and have them check to see if the replacement was defective or failed. If not, you may have a bad throttle position sensor [part of the gas pedal] I'm assuming it worked fine for a while after the repairs with no problems then suddenly started acting up again. I've replaced a bunch of throttle bodies but only one position sensor so far. There's always the chance that there's a bad wire somplace or some other more exotic problem but I'll bet you'll find it at either the sensor or throttle body. Good luck, hope this helps!
THE ENGINES THROTTLE BODY HAS A TPS WICH IS CALLED A THROTTLE POSITIONING SENSOR
It has a built in reostat inside of it which can get a flat spot anywhere in its circuit explaining why your car hesitates or sounds like it is ready to stall out
I would replace it and have the voltage set at 1.5 volts when set at the idle position
Then it should run fine again
O-2 sensor what is the cause of that, it is the one on the side of the throttle body in your book on the car it will also say Oxygen sensor, change it out it will be fine, The Jetta is a great car take car of her
