I'm getting the following error codes when I perform a diagnostic check on an SC400 ...
EFI13
EFI31
When it finally starts (!) the car seems to be missing an entire bank of cylinders. In addition, the catalytic converter warning light comes on as soon as the car is running. I've already replaced the fuel pump ECU but this doesn't appear to have addressed the problem.
Can anyone shed some light on what parts these error codes might be referring to?
Any help would be greatly appreciated, since the MOT is already overdue and I won't be able to get another one until I've got the problem sorted!
