Hi, have A3 early 2000 model 140,000 miles. had hesitation problem with car, sounded quite muffled and throaty if that makes sense. felt like even with foot hard to floor it wasnt going anywhere. not revving properly. blew head gasket, just replaced that but problem stillthere. dont want to blow gasket again so looking for advice. i have just realised that if car starts first time on key with no accelarator at all the car runs fantastic, but if i have to touch the throttle at all to start her thats when the problems begin...... the only option is to pull over and wait til i can start her without using the throttle. Any ideas???
