I have a 2005 Jaguar XJ8. Two techs with extensive knowledge have tried to correct multiple misfires with codes P0300, P0351, P0354, and P0356. The misfires occur after the engine has reached operating temperature and then the car has set a few minutes. The pinpoint tests in the Jaguar factory repair manual have been conducted without success, the last of which is engine control module failure.
Can your repair the engine control module for this car?
Thank you for reaching out. Unfortunately for this year and model we do ABS module repair and millage correction at this time.
Sorry for inconvenience
