Guys,

I don't know the status on my plugs (maybe the P.O. changed them recently, maybe not) so I plan to pull a couple for a look-see. At the same time, I was thinking of pulling the fuel rail and looking at an injector. If they're four-ports, they've been changed, but if not they could be a couple years old, or have 200K+ on them. Same with the COP's. Any way to tell by looking (date code, for instance) if my COPS and/or injectors are original or may have been replaced?

The older COP's have Green labels. 2000 + COP's have the Yellow lables.

Next they were all black with white letter/number markings..

 

Thanks, jbrew!

The one's installed are yellow (like the bottom pic), so I assume, being a '99, they must have been replaced at some point. Question still remains, then, when? Good to know at least they're most likely not originals.

That's the ones I'm running right now as well , mine came from a 2001 crown vic crate motor. Not even 6 months old and I've went thru 2 already. But that can be explained . My main gas supply line that plugs into the rail disconnected while I was driving her - Pumped fuel all over the motor

Yea , I sh^t my pants when I poped the hood to see that happening with my daughter in the front seat.

That stupid spring clamp rusted in two pieces on me ..

Anyway, I lost two COP's that way.

I had a set of older ones from a Mustange GT that I replaced the two with that was drenched in fuel.

BTW - I used a handful of McDonalds napkins to dry the chambers out - I temp repaired the fuel line on the side of the road as well, used my bootlaces to hold it stationary until I got her back home.

Your coils could be stock - I have seen both labels (Green and Yellow) on the 99's come to think of it. They may have changed lables half way thru 99..

So I wasen't really that much help. The order is right tho - Green, Yellow then Black...
