i searched but really couldnt figure this out my self.. my car has a wierd sound backfiring.. dont sound like a real exhuast backfire if u no what i mean.. and it feels like i got nos when i dont..like if i hit the gas ill get power but not full power then it will come all of a sudden.. i guess its called hesitation neways.. i think my timing might be off.. i dont have a light ill take it to a shop tomorrow prolly but i was just wondering if theres nething to do myself.. also could it be a bad spark plug wire?.. i have the accel ones and it was my first time making them and i didnt have the lil crimpimg tool i used pliers instead.. so yea anyhelp is appreciated! o and i didnt mention i got horrible gas milage.. like 9-10 a gallon
