Re: Spark Plugs
Get the boschs out. I had tried a set of those and after a month, the platinum tips were disintegrating. Although i currently have a problem similiar to yours(missing at low rpms at cruise up a hill), mine i know is my fordracing 9mm wire set. I am currently using AC Delco Rapid-fires but im told by Ford performance experts to only use Motorcraft or Autolites as you said, and not to waste your money on any of those fancy plugs. My last set of wires were arcing through the boot to the exh. manifold causing a miss and i know this warranty replacement set is now doing the same thing, but i haven`t pinned down which wire is malfunctioning yet.
Im also wondering if theres any *truth* to that plasma formation under my accel cap since their not vented like stock ford ones as mustangs and fastfords magazine tech article pointed out.[img]/wwwthreads_images/icons/crazy.gif[/img] Maybe i will try a stock cap and see.
But pull out some of those Bosch`s and with a good light and a magnifying glass, inspect that little platinum tip and im sure you`ll find them burn`t up just like i did.
Im running a Crane ignition system w/high output Fireball coil, but my wires were malfunctioning even with the ign. system bypassed.
