Having problems with your 1999 Mercury Cougar ?
ENGINE MISFIRE TO THE POINT, THE CHECK ENGINE LIGHT COMES ON. AN IT WILL START TO FLASH. AN WONT GO OUT UNTIL YOU TURN OFF THE CAR .60-65 IT WILL STOP, AS SOON AS THE CAR START TO SLOW DOWN.IT START ALL OVER AGAIN.
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.
