86 505 STI XN6 Restoration

It still has the plugs from 20 years ago in it, and they are black which matches what my dad said how the car used to run lean. I don't know if the running lean now will change the color of the plugs after being black for so long

Plugs would be white if it was running lean, tan is perfect, black is usually rich or burning excessive oil.

Plugs can also foul with it running so rich, so new plugs might solve a lot of the running issues.

BTW - How’d the injectors finally come out?

Took a long screwdriver, and stuck it into the crack around the injector and the intake. And just pushed as hard as I could, and slowly they came out. I bent the metal screwons, but I think it worked out ok. :D I think the temperature actually effected them coming out.
