What cause misfires in Lincoln LS?
Usually that is caused by one or more compromised ignition coils. Common problem on the LS. Water migrates along wires through to the ignition coils that are just above the spark plugs. Water rusts and thus compromises ignition coils. Oil infiltrates through gasket and soaks coils thus compromising them. Problem is reputed to be occasional, but I have a feeling that this occurs all too often. Many if not ALL LS owners suffer through this.
When changing the coils there are no numbers on the new coils so how do you know that the coils are in the correct spot?
The first coil is on passenger side by firewall and then go from there.
