I have been dealing with a misfire now since last fall but it never threw a code. It seemed to occur after the car was warmed up, usually on the drive home. It started as a slight chug and recently happened daily. Last week while backing out of a parking spot it was surging almost feeling like it was going to stall. Same thing happened this morning but FINALLY the check engine light came on and drove like crap. Dropped it off at the dealership today with 98k miles and mentioned the 100k coil warranty, the service manager knew exactly what i was talking about and agreed to take a look at it. I was expecting to have them deny and give me the run around. Just got a call that the tech found atleast one bad coil, possibly more and it would be taken care of. Whats crazy is all eight coils were replaced in Oct. 07 with 48k miles. Its amazing that the coils seem to have a lifespan of under 50k miles. I'm looking forward to seeing exactly what and how many were replaced for a 2nd time.
A couple side notes, i checked out a MKS in the showroom and they look really really nice up close. The exhaust still erks me but the interior is a big upgrade from the LS in quality. Also they gave me a Ford Fusion as a rental and i think those arent bad little cars, not so much for me but i would definately consider one for my wife. The ones with leather, sunroof and sync navigation are a great car for the price. I was very surprised.
