P0351, P0352, P0353, P0354, P0355, P0356, P0357, P0358 on a Jaguar XK8 (1997 - 1999)

The codes P0351 through P0358 are for ignition coils malfunctions. The symptoms are usually a rough running engine due to misfiring. 

Quick fix: replace the ignition coil that is causing your code. Just click on the link below to buy the coil and look below for a guide.

If you have the code:
  1. P0351: replace A1 coil
  2. P0352: replace A2 coil
  3. P0353: replace A3 coil
  4. P0354: replace A4 coil
  5. P0355: replace B1 coil
  6. P0356: replace B2 coil
  7. P0357: replace B3 coil
  8. P0358: replace B4 coil

Changing the coil is not that hard. I recommend doing it on a cold engine so you don't accidentally burn yourself and drop one of the tiny screws. If your coil is on the A side then you need to remove the intake tube. Then it's all about removing the coil cover (the cover with six little 7 mm screws), unplugging the coil, remove the two bolts securing the coil and pull it out. If the boot stays on the hole then you need to pull it our with needle nose pliers. But it's super easy specially in a cold engine. Your biggest concern is not dropping any screws.

Better fix: replace all eight coils. If one of your coils is out, then the rest are likely to follow. Just change all eight of them and you don't have to worry about them any more.

Best and true fix: replace all eight coils and spark plugs. This is called an ignition service and remember the older the spark plug the more the coils have to work. If you do this (which is kinda pricy I know!) you'll see slight improvements in power and fuel economy so you might want to consider it.

  1. Save some $$ and try swapping out the offending coil and plug with those from another cylinder and clear the codes - drive again and see if the OBD code moves with the relocation - if so you know its that coil/plug combo and go with a replacement strategy. However, if the code stays the same then it indicates a short somewhere - check your wiring harness to see if there's brittle insulation, a short, melted wiring, wires rubbing against something hot, etc. Its not that hard to swap out the coil/plugs and it could save you $$ to run this check first.
