I have a manual 2002 lancer. The only mod as far as the engine goes is a short ram intake. It is a 5spd and is just coming up on 110000 miles. In the last couple of thousand miles i have been experiencing this problem that has become progressively worse. When i get on or off the throttle, no matter how slowly and smoothly, the car lurches/bucks. I have no idea was is going on. This makes it hard to shift smoothly and also contributes it driving it being just on overall rough ride. I have no idea what is causeing this. In the last 10,000 miles i have done plugs and wires. Any help or advice will be greatly appreciated. thanks guys

 

I would suggest changing out the coil packs. Are you throwing a check engine light?

 

no there is no cel i changed the coil packs and it made no difference
