Help wth hesitation problem when i am going at 80 to 120klm i get alot of hesitation on the highway.

 

A little more info on your car would be helpful- year, engine, mileage, etc. Is this the only speed you experience hesitation? How frequent is this happening? Have you kept up with the reccomended maintenance? If you have not kept up with the maintenance I would suggest doing so. I would check your fuel delivery (filter, pressure, etc.) and spark. Do you have bad/fouled plugs?
