sparkplug wires.
Still diagnosing a bit of a rough idle and got around
to the plugs/rotor/cap/etc. Rotor and cap had signs of arcing and oil spots but no traces of oil in the distributor base. :/ Oh well, replaced them anyway. All plugs came up with trace carbon and otherwise perfectly normal tips. :) At least with the new header I'm no longer running overly rich. So, just for grins, ohming out the wires. Hoo boy, first thought was I f-d up, but the Fluke-87 autoscales. Plug length resistance ohms/in 0 8 283 35 LOW 1 12 501,000 41,750 HIGH 2 10 105,000 10,500 HIGH 3 15 6,500 433 GOOD 4 14 12,200 871 GOOD 5 10 4,920 492 GOOD 6 13 479,000 36,846 HIGH Well, that's all over the freeking board now isn't it. :/ Could explain why the last coil died a horrible death. Gonna get a new set o wires tomorow and measure them first. With any luck that will get it all working nice and smooth again. (If it does I'll post a warning about flying livestock.) ^_^ FWIW, they were BOSCH wires, not the cheap ones. So much for "Quality", I'm going back to OEM or at least NAPA Echlyn. -- DougW |

I have had the best results with OEM over the years.

Re: sparkplug wires.
Sometimes it's hard to get a good contact point on the wire connectors. Any
oxidation on them will take away from your measurement. And DON'T touch the probes with your fingers (pinching the meter probes to the wire ends) this will just incorporate your body resistance in to the reading. SOMETIMES this has been a problem for me. (big sweaty salty guy!! haha). Just a thought.
