I recently had work done on my car. They disconnected my battery as evident by needing to reprogram all my radio stations. When i left the shop the car stalled and died a few times while slowing for stop lights. I had to rev it a few times and it seemed as if the car was learning how much throttle it needed to give. That was a week ago and now the car seems to run fine, except it doesn't seem to give enough throttle when cruising off the pedal. Sometimes the car jerks back and forth if i don't give it just a little gas.
Is there a procedure to properly re-calibrate the throttle by wire system?
i have a 2008 impreza 2.5i 5MT.
