I have gone to multiple mechanics with no help. My vehicle surges or revs any time the ac is on to the point that the vehicle lunges forward even when my foot is on the brake. This occurs in neutral, drive and park. It specifically occurs when I am slowing down, stopping, or coasting at a low speed. It also jerks when in drive but not applying the gas, then revs with no warning. No check engine or other lights are coming on. I have been on several Mazda forums and this seems to be a recurring issue wth this vehicle. It has caused me to hit a wall (I was slowing down, coming into a parking space) and my neighbors vehicle as I was waiting to turn right out of our condos.
