Hello,
I put in magnacore wires about 3 weeks ago, but I am still getting p1316 and p0308. I am going to get new plugs in soon but the plugs that are in there now only have about 20k miles on them (champion). If the bosch +4s don't resolve the problem (and I have to fix this due to inspection). What other things could this be?

 

Have youpulled the plug in #8 to see what it looks like? could be a bad injector...

 

Are you talking about a D2 or D1, what year and how many miles on the truck?

 

I will take a look at number 8. Is there a special tool that makes it easy?

edit: '96 disco 118k. I know its getting close to needed head gaskets / valve job.

Nothing personel, but it sounds like you are a little limited on mechanical area, if that is the case, call me and I'll walk you thru what to look for.
