In this wonderful age of electronics the fix is a simple reflash of the igntion mapping contained in the PCM.
Exactly right. I have "flashed" (as we like to call it) many Focusus. This should be done to Every Focus in Pre-delivery with a build date before the 4/11/02.
Bammas: How long have you had the car for? I'd be checking the build date and if it is biult before the date i posted above then go talk to you dealer.
