There is recall on mercury cougar 1999 v6 for a fuel filter that may cause hesitation, stalling, surging. Over fifty times has this occurred nearly causing serious accidents over five times. The car has been given a "tune up" to eliminate that as the cause. The only other cause could be the fuel filter which has been recalled as per recall 04v421000 the federal safety agency. I have contacted ford and ford dealerships and they refuse to deal with the problem. If this has happened on other vehicles then it is the cause on this vehicle whether they want to admit to that or not. This needs to be fixed before someone gets seriously injured or killed.

I was commuting to work in mountainous terrain and while traveling uphill, the car lost power and then the engine quit completely. I was barely able to roll the car out of the highway before another vehicle approached the blind curve from my rear and swerved to avoid the broken down car and myself. I conducted an internet search after finally getting the car restarted and returning to home that evening and discovered that ford motor co. Had initiated a program to alleviate the symptoms the car was experiencing. Although the car behaved exactly as described under the manufacturers description of potential problems(including surging, hesitation, loss of power, and engine stalling), I was told after contacting the selling dealer and ford that my car did not qualify for any assistance because it fell outside of the production window of the vehicles they had identified as having similar problems. This problem has recurred 4 times since the initial incident while driving on inclined surfaces but I do not attempt to drive the car on the mountain roads. The extended coverage program 04n02 is the program I referred to when contacting both the dealer and ford motor company. As a result of this, I am unable to use this car to commute to work and have resorted to the use of rental or borrowed vehicles.

After doing some research , the consumer came across a bulletin which described the problem he was experiencing and a resolution, which was a defect in the fuel delivery module.

I own a 1999 mercury cougar. I have maintained the vehicle per the service manual through the local mercury dealership. Sometime during early april 2005, I noticed that the car hesitated and jerked violently after about fifteen minutes of normal driving. We were able to drive the car in for service. The dealer "diagnosed" the problem and replaced a part. The car continued to malfunction the very next day. I returned to the dealership and was told that the problem was with transmission. I have had the transmission replaced by a local ford dealership. I am not sure whether the old transmission is available.

Recall campaign 04v421000 concerning fuel system gasoline. Delivery. I am experiencing these exact problems, which are believed to be present also, by my local dealer, where I showed the car to a mercury trained mechanic. However, ford/mercury (ron bluestein/ford executive offices, id # 2170, phone 800 521 4140) refused to cover repairs due to VIN .I strongly disagree and fell that my car's safety was in question. On certain passenger vehicles, contamination of the filter in the fuel delivery module (fdm) could reduce, and eventually block the flow of fuel to the engine. This may cause engine hesitation, loss of power, surging, and other similar symptoms. Sometime, the filter may become sufficiently blocked to cause the engine to stall, which could result in a crash.
