WE have a 2003 Mercury Mountaineer that had a misfire code for cylinder 6, we replaced the coil, igniter and spark plugs, and still keep getting misfire code for that cylinder. What else can we do?
What do we do next?

Make sure the fuel injector is getting power and make sure there is good compression in that cylinder.

thanks for the reply, our mechanic has to order the machine to check the compressor, if it is that do you know how much it will cost to repair?

If the compression is low in that cylinder, you need to determine what is causing it. it could be a bad valve, worn rings...
