About a week ago, my Disco started really struggling and vibrating. It did not take me long to deduce it had a misfire. I bought this LR used about 7 months ago. In that time, I have put new Magnecor 8mm wires on it as well as changed fluids and the like. I replaced the plugs a few days ago with Champion Platinums (gapped at .035). The old plugs were not in good shape. That helped a little but I still have the misfires. I always run 93 in the tank and I cannot vouch for what it had run in it before I bought it. The codes are as follows:
PO300
PO304
PO306
PO308
PO314
PO316
So I clearly have misfire issues. I did some searching on here but did not come across the amount of misfire codes I have here. So before I start slinging parts/money, my questions are this, is the coil the obvious next place to go? Would I get multiple misfires on only one side (cyls 4,6,8) with a bad coil? I read somewhere about the vehicle speed sensor having issues, does that have any bearing on this? Any help you guys could give me would be greatly appreciated. Any questions you have that I did not cover here, I can answer quickly.
