Had my waste gate solenoid replaced under warranty a couple of weeks ago when serviced at 10k after complaining that the car cut out momentarily when on full throttle, the car is a WRX 03 PPP. Now when you accelerate hard and then back off the throttle quickly the car sort of jerks quite badly rather than decellerating smoothly. It dosn't always do it, does this sound like a sticking waste gate?

Does anyone else get this? - any advice please. I'm sure it didn't do this before.
