ok ive got cel misfiring on my cylinder. ive changed the spark plugs and they work fine after that then after say a coulpe of weeks it pops up again. i thought it was my spark plugs again so ive changed it three times now. i was thinking my fuel filter but i dont think it is. ive messed with my timing belt installing a lighter pulley but recently putted the stock one back on. So if its my timing, how would i fix that to make it right again?
ps. dont tell me to look around the threads to find the ans. ive tried and failed, miserbly
