After having “tried everything”, I am seeking wisdom on this issue I’m having with my 2000MY XJ8 3.2 litre.
The car does not perform properly. It will start and idle but will not perform properly when driven. It seems to be missing continuously on one particular cylinder on each bank (even on idle); I can tell by the even exhaust stream being methodically interrupted thus not running as softly as it should.
Since I picked the car up last spring, when it was barely running at first but picking up as the journey progressed and with the addition of more fuel and jeg cleaner, I have replaced the spark plugs and all the coils to no avail.
The engine was replaced under warranty (not nikasil at this late MY) at 60K miles, and it currently stands at less than 120K miles.
Any insight would be greatly appreciated!
