wow.
I won't get in to this, but I will say:
RESEARCH THIS before you buy +4's... APP764 Autolite Double Platinums, or Motorcraft (PPM plugs, not FM) (they are identical to the autolites) are the only plugs you should use.. Of COURSE there are others (NGK, etc) but at three times the price, etc, autolites are THE recommended plug. (DOUBLE platinum..
Gap to 0.054
I know that the original poster already used the correct plugs (and wires!!!), so this does not help the PROBLEM, I thought that I should step in before someone ELSE reads this and buys the +4's.. GOOD LUCK TO YOU, sir, if you have any good results with the Bosch POS's.. (LONG TERM results.. ANY plug fires GREAT for a little while.)
