Well that's why I kept changing all the plugs even though they looked fine, replaced with the same Motorcraft ASF 42 whatever stock plug, 0.054" gap. I paid extra attention to making sure all the plug boots made good contact. The fms 9 mm wires I have don't snap on really obviously, one wire I actually had to pinch the end tighter to get a better click feel. None of the plugs were black, but any misfiring there would certianly cause an increase in HC emissions. I did use some anti seize on the plug threads this time which probably gave me better ground.
I too thought an Igniton module was go/no go affair to but figured the plugs were not any problem and only 2 deg timing is no big jump. I was beating on the car today and it pulls better up to and past 5000 rpms now. I also changed the PCV screen that looked pretty pluged up! While I was at the dealer trying to describe the screen, a tech in line in front of me said " those are in crown vics below the PCV, when they plug up the motor blows every gasket since it cant breathe"
HMMM I have had a leaky oil pan gasket, and it gets worse when I jump on it, and will get oil on the cats, and smoke. After tonight , no smoke hmm, sounds pretty good to me for $7.00 I would have been pissed if I blew a new pan gasket, still got to change it out, but now know why it started to leak.
One bummer is the O2 sensors would not budge for me today, The 7/8" special O2 sensor socket fits tight on the new Bosh ones, but could not turn the ones on the car even after soaking with PB blaster. I knew I should have pulled them out when the H pipe was on my buddys shop floor!!!!!! Looks like a job for the big red wrench! Or anyone in mass have a stock 86-93 H pipe they want to give away??
