Ok I'm lost again. My husband and the subaru dealer said my car was acting fine now that they reset the computer. I drive it for about 5 hrs afterwards and the engine light turns on and we're having the same problem again. Guess the throttle position sensor didn't work.


Here's what it's doing.... when I stop... sometimes not all times... I can depress the gas and no matter how much I push the pedal it will pull out at around 5mph. When it really acted up I even tried flooring it and the car crawls away 5mph then all of a sudden it acts like the gas kicks in or the engine realizes that I'm accelerating and it jumps.


Any ideas are greatly appreciated. Haven't run the codes yet but I will asap and keep you posted.

What's the code this time? Please post the actual numbers, P0XXX, not the wording the scanner says.
Did the Dealer actually calibrate the TPS or did they just reset the computer?

Symptoms are similar to what I would expect from a large vacuum leak. Are you sure no hoses got knocked loose during the parts swap-fest that took place just a few days ago?

throttlebody cleaning? could the throttle plate be sticking this badly?
