P0308 Cylinder 8 Misfire

[jj970]

Hey all...

I married a girl and she had baggage...a 2000 Discovery with 130,000 miles.

We've now had a failed driveshaft, bad O2 sensor, head gasket leak, waterfall effect and a few other issues.

2 days ago got P0308.
Changed the plugs yesterday and still have the issue.

I don't really want to waste time and money on this beast anymore, but can't have her driving around like this. It's still got power, but idles rough. No overheating.

Do I have to change all the wires? Can I just buy and replace #8?
Anyone every heard of just buying one wire?

The problem is that I'm in Chicago and she's in Indianapolis right now.

Thanks for any advice.

As you will find out, if you have to change one wire you will want to change them all so you don't have to do it again. A royal pain in the *** . Could also be a dirty air filter or dirty MAF sensor... but that would all depend on the last time you or she changed the plug wires.

Was just feeling like I can get the energy to do one...but to do all 8 sounds like a pain.

I don't even have all my tools here.

Seems like it's a ***** to get the wire off the coil connector without a long screwdriver or other piece of metal.

Small hands and arms are best...
