Ok so ive have been trying to figure out what could cause this but my 98gt when accelerating hard from a dead stop or rolling start but the car will lanch hard and then when its at about 4-5k it will bog way down like i shifted from first to 5th! Any ideas what it could be? i have replaced the plugs,wires,coils, IAC,TPS,cleaned mass air which is a pro flow.
