Hi There,4 months ago i had a bit kind of power lacking problem in my Hyundai Excel Sprint 99, and i took to the workshop where full service was dont including the new spark plugs and its wires changed. There was a bit carbon on the tip of spark plugs but no oil leaking. It was ok until 3 months later the same problem and the same way solution. After that it lasted only 2 weeks and the same problem now. Can anyone help me in this matter? This mechanics will gonna rip me off if i take it back again.
