Well today I took the car to the Ford dealer. One of the rear oxygen sensors is bad plus the mass air flow sensor. Total work $505.00, needless to say I paid my $55.00 diagnostic fee and took my car home. The dealer told me that one of the rear oxygen sensors went bad and that sensor was very hard to get at. Which rear oxygen sensor is he referring to? How hard would it be to replace this oxygen sensor? The Ford dealer almost wanted $300.00 to fix it.
The dealer also told me that the mass air flow sensor was reading 149 and in Houston it should be reading 155 (see level). A reading of 149 is what the mass flow air sensor should be reading in an altitude of 2500 ft. Does any of this make sense?
Any help would be greatly appreciated.
Thanks
