Need to replace the #8 injector. Would the 2000 Excursion come with AD or AE code injectors in the #8? Which injector code would be best to use?

Thanks!

 

Just out of curiosity what is making you replace it? P0308 routinely popping up? Has it failed a buzz test or similar?

With the dead head design, it's not uncommon for a #8 misfire to occur. I installed an FRx first before replacing the injector as I kept popping a misfire for it - solved the problem.

Running the same code injector as the rest is what I'd do, and you should have AD bodies in it IIRC. I believe there was a TSB that installed an AE body in #8 to help with the cackle and longevity of the injector itself - this requires a PCM flash.
