I have a Jaguar XJS cabriolet V12 from 1990. The engine runs rough like on 11 or less cylinders. Upon checking the sparkplugs it was clear that all cylinders have fired but just in case I changed the whole ignition system. When checking the CO2 levels it was clear that it was much higher at the right pipe. I have also tried with injection cleaning fluid if the problem could have been clogged injectors.
have the same problem?
