Answers :

Wait untill its dark outside, open your hood and start the engine. look around for white / blue or yellow flashes of light coming from your plug wires. most of the time the spark plug wires are worn out / degraded from heat , and you can see the small lightning flashes in the dark. if you see no light flashes ( shorts to ground) then you can have a cracked / faulty distributor , or bad spark plugs.
