was driving home from ollie ryans house last night, and was cruising on the m'way about 65mph, put my foot to the floor to overtake a lorry, and my car decided it didnt want to over take the lorry and didnt gain anyspeed, or lose any, but it sounded like a scooby popping like crazy. but it was on and off it wasnt just a constant noise but today it has got worse and when i put my foot to the floor now, it accellerates really slowly, and the exhaust burbles like a mofo! constantly but if i bring the throttle back up, it stops not sure whats wrong, anyone know what it is or had the same thing happen to them? thanks in advance ryan
