I just bought second hand 04 optra 1.8. The car dealer gave me a new set of timing belt. Mileage is 160k km. The problem is RPM not stable when idling or slowing down. Can jerk sometimes. It happened sometimes only and not all the time. 2nd problem is my wiper cant blow water. Got sound but no water come out. When first buy got water den after a week dun have. Appreciate if anyone can help. Thanks..
