I own a Ford Focus 2001,zx3 for 59,000. The check engine light came on 6 times now! 2 for a dpfe sensor out, 2 for egr presser valve. Also started to stall,buck and surge at 35,000 miles, and found out the fdm had to be replaced. That lasted for a short time which the symptoms came back, and the fdm was replaced again. I have had to deal with inconvenience and the last repair which was dpfe sensor which Ford picked up 50% of cost but this car is a lemon! I also had to replace the ignition switch when the key would no longer go in. Now the check engine light is on yet again and I have to go back to bob baker Ford.
My car has 29,500 miles on it. I bought it used about 3 weeks ago. Following symptoms: 1 - car stumbles/hesitates/loses power at around 2-3k rpm. . . Regardless of speed. . . But stumbling/hesitation is best felt on the freeway. 2 - car has had some type of recall work and dpfe sensor replaced 17500 miles. Not sure if fuel pump recall has been performed. . . Ford dealers have been very reluctant to tell me without making me spend $150+ on a stupid diagnosis. . . That's called good business. 3 - dpfe sensor replaced prior to me picking up the car 28440 miles. 4 - 1000 miles later. . . I have the stumbling. 5 - things I've done to the car: a - replaced air filter b - replaced fuel filter c - replaced pcv valve d - replaced plugs (using bosch platinum 2) so far I've done all changes myself because no Ford dealership seems to care to offer advice or a helping hand. The consequences are that I've almost been hit from the rear due to stumbling/hesitation.
