not likely a fuel issue,
try running it in the dark of night , no lighting and look for sparks ,
have the ignition coil tested , be sure it has good ground.
pull each plug and watch the spark ,does it maintain the blue long arc.
tune a am/fm radio to the sparks ignition sound an listen to it
a portable walkman can lead you to the faulty spark,
or just have them monitor the spark at the shop.

You may need a new wiring harness. They have to be ordered from Germany. This is my guess. (I am having a similar issue with my '94; rough idle, #4 cylinder not firing intermittantly, replaced plugs and 8 ignition coils; new harness is my mechanics guess)


cheers and buena suerte

Might be the fuel Inj. or spark plug. I had the same prob on the #7. Changed Pack, inj, and plug and it fixed it.

Can I get a spark plug wiring diagram for a 1998 land rover range rover 4.0 V8? I can't find anything by googling it..


There is a single High Tension Lead that goes from the spark plug cap to the coil pack.

Or do you mean firing order from coil pack to plugs? Which wire goes from what cylinder to which coil?

I was having a problem with the engine cutting out, so I changed the spark plugs and filled the tank with good gas and fuel injector cleaner, and now it is missing worse than before. What is the problem?


it could be anything but i would say you should check the ignition coils first. you can do this by testing the resistance in the coil packs. make sure the engine is off and the key is not in the ignition. if you set your voltmeter to ohms take the 2 ignition wires off of one coil pack. touch your voltmeter lead wires to the 2 posts on the ignition coil. it should read 4000-8000 ohms if you have a bad coil it will usually be close to 0 ohms. do this test for all coil packs. each coil pack ignites 2 cylinders so if you have a v6 you will need to test 3 packs and 4 packs on a v8
