So my XKR 4.0 (2002 UK model) previously had the P0400 code back in April:
I did a clean up with carb cleaner and the error code never came back… until last week (i.e. 6 months later). Typically, as I’m trying to sell her…!!
So, I did the same clean up. Error went but I felt the engine sounded ‘rougher’.
Today, engine warning light came back and I checked my codes… HORROR!
P0303, P0304, P0305, P0306, P0308
Eek. I’ve done some googling and get what these are all about in general… I guess it’s unlikely to be the spark plugs as there’s 5 different ones showing; wasn’t sure if there were individual coils for each cylinder (some of the posts I read were for different model cars/engines) or a single coil pack? If single coils then again I guess it’s unlikely to be the coils… but is there one ‘pack’ that covers them all on this car? Similarly, I guess it’s unlikely for it to be spark cables as they also wouldn’t suddenly all go at once would they…?
Any advice greatly appreciated!!
Also… should I be driving the car at all??
