ok so the car is a 98 civic lx with a d16y7. i just replaced the head gasket and its runs very smooth but it doesnt drive. and what i mean by that is that the car will move under its own power (its an automatic) but as soon as i give it some gas it will bog down really bad. if i kept my foot on the pedal it would stall out. also it will let u use the gas very small amount until 2k rpm and then the car will start to buck unless i put my foot under the pedal and pull it so it can stop any tips help. and before anyone asks there are no lights being shown on the dash.

Also helpful replys will get REPD
