On my 93 GT if driving it normal its fine but when i get on it say 3/4 to full pedal it has this weird bucking almost surging feel to it...almost like a miss but its not...Could it be timing? TPS out of wack...you can actually feel the car stumble while floored its annoying you hear the car cutting out to when it does it...It has new plugs,cap rotor,wires,fuel filter..K&N drop in filter...i cleaned the MAF now i did notice sometimes the car idles low and then sometimes it idles normal...wonder if that has anyting to do with it..I feel the car can be so much more responsive if it didnt do this surging..Oh yeah its an AOD car and it does this in 3rd or Over drive too....any ideas? thanks...
