guys:

i parked my GS3 for a while then driving around; right after stop light when i push on the pedal (slowly as I don't drive fast), the rpm slightly increases then around 2000 rpm (approx. 20 mph) suddenly i felt a jerk

this happened couple miles down the road at another stop light...one more time...(right above 2000 rpm)

then for the rest of next 20 miles, I did not feel this anymore;

does anyone have similar experience??

 

Was the car at normal operating temp already? There is a slight hesitation when it is not, at least on mine it behaves this way. Once the temp is at "normal", it behaves fine.

 

Neo:

thanks for the response..

it was after being parked for 1 hr or so....then the second hesitation came 5 min or so after the first (both after a stop)

what confused me was that I never felt this eventhough after overnight or long hours (5 or more)...???

 

actually hesitation may not be the best word to describe it, since it's more like sudden jerk that slammed the car forward...

 

i hate to say this but without driving your car, and by what im reading, it sounds like the tranny.

 

it's ECU reprogramming (dealer confirmed) and solved the problem; this is common for 01-02 GS

 

thats great...could of been alot worse

 

Is it related to this TSB?
