[x300] My 1997 xj6 300 model

My instrument cluster all the gauges will keep on flickering
from working to non working then going back to working again

Also when I stop at traffic lights the check engine light
will flash on for an instant… the engine will give a little
splutter then pick up again but never stalls no codes ever
come up when I plug in my OBD11
any help on these two problems please–

Almost certainly you have at least one ignition coil failing.

These threads might be of interest

I am now having the same problem. Dash indicators and dash
lights sometimes flash or go dead then come right back to
normal. Did you fix the problem and how?–

Jaguar issued several TSBs for your Sedan Model. I remember
repairing these faults when I worked at the dealer.

Look up TSB 15-12amended and 15-34.

I would post them here but there is not a provision to
attach files to this post.

Fixed at last!!! After 3 years of sitting in the side driveway because of the instrument flutter/stalling problem, I read one of the replies by a “motorcarman”, a Jaguar mechanic who remembered seeing this problem in the shop one day. He said it was probably a bad spark plug coil feeding a spike back into the ECU. Sounded too simple, but I decided to try pulling plug coil connectors one at a time when this problem would start up (usually about 5 - 8 minutes after a cold start). Plug #6 coil was unplugged when the system started acting up and magically the engine started purring like a kitten even though running on only 5 cylinders. The bad coil (a cheap replacement installed about 7 years ago) has been replaced and the problem is FIXED. Yes, it seems like the cheap, faulty coil was causing the ECU to re-boot and that was the problem.

I remember posting about the fault we had at the Jaguar Dealer when the coil pack interfered with the ECM.

Glad you fixed your issue.

Thanks, motorcarman, your little snippet of remembered information is pure gold. It not only saved hundreds of dollars, but maybe even a final trip to the wreckers for this beautiful vehicle.
