The coil packs are known to be sensitive to over-heating. Once the engine is significantly over-heated, the coil packs might be damaged such that they are prone to intermittent failures which might be hard to troubleshoot. The engine might or might not need to be fully warmed up to see it happen.

If 1 & 3 never or rarely show misfires try swapping those coilpacks and see what happens.

Are you using a code reader that will read LR specific codes or just an OBD emissions reader?

I'm using the readers from the mechanics at work. I've got to program the make, model, year and all that good stuff so I'm assuming it is reading Land Rover codes?

As for the overheating that makes sense that the coils might be starting to wear. I try not to drive it too far, but it's been needing a new water pump for over a year now so it may have just finally caught up.

Default Diagnose with ALL available OEM codes!

A full set of OEM codes makes diagnosis easier. You need to give us all the codes, including not related codes, since these often throw codes that are causing the problem but appear not to have any relation to what is happening. Don't just chase individual codes as that can cost a lot of unnecessary expense.

Suggest you check your battery and alternator. When you get an assortment of codes and operating problems, it's good practice to eliminate the battery and alternator as the root cause of problems before proceeding to diagnose other components. Insufficient or erratic power can create puzzling symptoms in modern vehicles which rely heavily on sensors and computer control.

How do you know it needs a water pump?

Those normally either leak, or do not leak. They either pump water, or they seize and do not pump water. On modern cars with common belts (including LR2) a seized water pump will take out all the other accessories, alternator, AC, PS.

Are you seeing codes starting with B1, C1, P1 and U1? Those are OEM specific (there are also others).

That is an incorrect assumption. List the codes. We can't help if you keep them to yourself.

I'm not a magician or psychic. Take it to a shop or an auto parts store and have them read the codes from the computer, then post them here.
