So I've been recently trying to diagnose what could ultimately be a misfire (didn't think so at the time), and so I used a Ford scanner to retrieve codes and what I got were 18c and 67o.
One of them has to do with each and the other is the neutral safety switch I think. On the NSS, the truck was in neutral (5-speed, no parking brake!) and I read that if the clutch wasn't depressed during the KOEO test, it could throw the code. True?
On the other code, it's worth mentioning that I've tried three different TFIs, one a brand new Motorcraft. It could be a fault in the wiring and it could also be the PIP. Does anyone have further information on that?
Ill be testing for a misfire next weekend, I figured I'd like to gather some information on those codes from knowledgeable gear heads on this forum in the meantime.
Thanks!
