Lumpy Running with restricted performance indicator

Lumpy Running with restricted performance indicator
Hi All,
Can you help me with these error codes, please?
P0830 Cylinder 8 misfire.
Am I correct to assume that the coil pack for cylinder 8 needs replacing?
What is the best method to test this, where is a good place for parts and would used parts be advisable for this?
P1316
I'm assuming this is in relation to the above error?
P1797
Low battery? Has possibly been sitting for a while what is the best way to test this?
Also, would this cause the parking brake light to remain on even when the brake is released and the window not to close fully when closing the door?

Check the misfire by swapping with another coil and see if the code moves.
Have the battery load tested at a local parts store. A weak battery can result in strange codes and also affect windows.
But also do a window reset- Press down and hold until you here a click, then up until the click.

Since you have a 98 XKR I expect you are on the other side of the Atlantic from me, but you may want to add your location in case there is a local member willing to assist.

^^ What he said.
P1797 is a CAN token fault and can be caused by a weak battery.
The handbrake warning light is likely a sticking switch. See this thread:

Member Gus' website is a great resource for information. You will find DTC code information here:

Okay charged the battery, sorted windows, may still need to replace the battery though.
Can any body tell me how I can test the coil pack with a meter as the fault code has not come up again since I cleared it but I'm still getting lumpy running?
Also, how do I get to the switch on the handbrake, do I need to take the seat out?

P0830 doesn't exist. Presumably a typo for P0308 which is misfire on B4 (8)
Possible causes of the related DTC P1316 are:

Presumably you've used a generic lookup for the DTC code descriptions? This is often misleading. For the 1998 XKR, P1797 is a transmission error code:

I've always removed the driver's seat to access the handbrake switch and harness.

If I've followed the trail here, you have a consistent fail on Cylinder 8 confirmed by coil swap and also found oil in the plug hole well.
I don't have a photo of the Ignition Module but the illustration (see item 3) from JEPC should help identify them:

Oil leaks from the cam covers is a regular issue. The main perimeter gaskets fail (usually at the rear) and also the spark plug boss seals (O Rings) which allows oil to leak and collect in the plug hole wells.
