Jaguar 2003 Xtype 2.5L misfire when cold
So, I have a 2003 Xtype 2.5L and on cold mornings it misfires on all 6 cylinders until the engine gets warm. It only happens intermittently when the temperature drops below 50F (10C). When I apply acceleration in neutral (or in drive) there is a 3-6 second delay in RPM increase, once above 2500 RPM the misfire stops, then when I let off the pedal and the RPM returns to idle it begins to misfire again.
I've replaced all six ignition coils, IMT seals, cleaned both the MAF sensor and throttle body, and I've smoked the system for a vacuum leak with no success.
The only codes my OBD2 throws is a misfire on all six cylinders and running lean on bank one and two. (Also bad catalytic converters, but that's a result of the misfire.)
I only know enough to be a little dangerous, which is why I've finally broken down and decided to come to the experts. Any and all help is appreciated.
Thanks,
