Question about 2004 Lincoln LS
2004 Lincoln LS -- running rough at 50+mph when accelerate-- dtc indicates coil problem-- how to tell which one?
I went thru this on my 2002 LS as well.
I replaced one ignition coil at the dealer - only to get the same misfire code on another cylinder. After a little research found out is actuall a gasket/o-ring problem design of the block. Spark plugs are deep in the block - under the oil - which is why they are supposed to last 100,000 miles. But the o-rings start to leak some where between 65k-85k miles. Coils go bad because of oil contamination. If you don't solve leaking oil problem will have to replace coils again - but sooner - because leaking oil will be progressively worse.
Cost - 8 ignition coils
set of spark plugs (who knew they were that expensive
and a ton of cash for the labor to tear down the top of the motor

Bikerflapper again: thanks warlock. I took it to the dealer tonight. The PCM is still under warranty and I think it may have a problem. I will post the results when I get it back

Does it still run rough? These do have a tendency to damage the drivers in the PCM.
