Question about 2003 Lincoln Town Car
2003 LINCOLN TOWN CAR 150k Misfired cylinder 6, replaced coil, plug Misfired cylinder 5, replaced coil, plug Misfired unsure which yet, all of these happening within a week. It will run fine for a day or so after replacing coil, then will misfire again. I've read through some if these solutions, what should be my next step? Thanks.
Change all plugs with proper ones - they are picky for some reason - do not change number or brand from original - coils were probably ok, - get some injector cleaner and run through it but check for exhaust leak at e g r tube - is a common over looked cause of misfire - a thing to keep in mind is misfire isn't always spark issue. hope I was of some help

When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.

Replace the coil pack once more. I went through 2 new ones on my f150 on one cylinder. One worked, the other didn't (both new off the shelf). Condensation build up in the boot caused mine to misfire. Anytime you replace a coil pack, squirt a little silicone grease inside. This will prevent condensation from hitting your plug. Fords are notorius for this problem, especially if you live in a humid area. Also, make sure and clear the codes after you make the repair.

A bad coil pack can foul out the spark plugs. I have also been told the computer might need to be reset for around $100. You must use Motorcraft OE plugs for this car to run at its best is what my mechanic told me.
