NOTE: The wires are Ford, grey originals with smooth silicone based jackets, not dry at all.
One guy on a Ranger forum suggested having a Ford dealer do it. I imagine he believes any chance of complication would be lowered and, perhaps, any which could arise would be remedied for no additional cost.
1) What would you do? please, just rattle off opinions
2) Does anyone know if copper based or nickel based anti-seize would perform better?
So far I've been periodically dripping Kroil (a penetrant) on the plugs' bases.
I hope this post doesn't constitute a thread highjack.
Ford tends to be picky about the plugs, I'd just get the motorcraft ones and change them. Not sure if it was used on your car, but they also used a waste fire system so they fired twice per cycle, once also on the exhaust cycle. I remember changing the plugs on my Taurus at 80k and the plugs were worn even though they were supposed to be 100k plugs. They weren't completely worn out but it wasn't like they looked like they were brand new and mileage did increase a little bit afterwards as the gap had opened up. Misfires are usually from plugs, wires and coil packs. And it doesn't take long for a misfire to burn out your cats.
