“While driving the car it misfires it doesn't want to go on acceleration..it is leaking oil into the spark plug wells and affecting coils..there was a extension warranty on these parts.but it was 10 years or 100000 mile . I didn't purchase this car till after it already had more than 100000 miles so I was unaware of these extensions and time frames..I spoke with ford/Lincoln and basically told the extended warranty would not cover.I feel this should be a recall not extended warranty.”

“Hello, I bought a 2003 Lincoln LS and I'm getting a message on the dash that is saying etc fail safety mode and the car is not able to go over 30 MPH, and has very slow pick up and is running very hard. I have found that sometimes if I turn the car off/on the message does not come up the car drives normally. I have tried replacing the throttle body after getting the check engine light came on with to codes p0207 and p02110 and I'm still having the same problem. I have read allot of complaints about this problem with fix.”

“Car hesitates on acceleration since it was new. Took the car to the selling dealer and they could not find a problem. The condition got worse. When traveling down the highway the car starts bucking and misfiring. Took the car back to the selling Lincoln dealership (sesi Lincoln mercury). They dealership said the drivers door needed adjustment. This made no sense to me and did not fix the problem. The car went out of warranty shortly after that. Now check engine light comes on intermittently and car hesitates, bucks, stalls and runs rough, misfires at highway speeds, and mil starts flashing. …”

Underneath hood the same, hadn't look as if been driven. Exterior body and paint again excellent. The car appeared as if it had stood still in time. Upon investigation, only one owner of the vehicle who'd maintained a first class maintenance record. Over the last week the vehicle my wife was driving she said while driving the vechicle began to stall while she was accelerating in traffic. …”
