Hi, I've had a good run in the car today and mo probs until after a few hours when the car seemsto be reving high when I'm stopped at lights etc, give the throttle a blip and it drops back to normal also when I'm changing gear 3rd and 4th mainly it judders like it's going to stall and the stop, temp and green gear lights come on then go off again, I then noticed they flicker slightly, then all back to normal when I turned the car off and back on again for another run bit then final run it's at it again! Any help would be great as I'm new to these cars, it's a 172 ph1. Thanks.
