I Have a 1999 Grand Marquis that's misfiring losing power high fuels smell come from tail pipe. While driving for a min check engine light blink on in off put it on a machine in it told me


If you have no exhaust converter:

You are violating Federal Regulations
You can not go to inspection
Your poluting the air
You have no place for your oxygen sensors to go,so you
have no fuel control at all & thus it has a misfire

No vehicle can be used like that

There is no test equipment that tells you what is wrong

You have to use the data to find a problem

Why would there be no converter on the car?

The coil keep going out


You may want to check the spark plug, if the plug is really bad it can cause the coil pack to fail. Also try a higher end coil pack as well. If problem continues to exist then I would take it to a professional mechanic.

How do i change spark plugs on 1999 grand marquis


Remove the coils one at a time and replace the plugs under them. The coils are tucked under the fuel rail but you don't have to remove the rail, the coils will come out.

Where are the spark plugs located


On these models Ford/Mercury included the coil and the spark plug wires in one unit. The coils are black and round, they have a wire connector to each one. In order to pull the coil, you need to disconnect the wire and remove the bolt holding the coil pack in place. After doing this, you can pull the coil pack out; then you can pull out the spark plug with a 5/8 spark plug socket.
