So I finally got the supra timed correctly and now I came across yet another problem. When the car starts it runs pig rich. RPM'S rise at like 2200. When the car warms up the idle drops to normal but is very lopy like it wants to stall almost like its chugging. I pulled plugs and checked them and they are black as all hell. Also at steady throttle it breaks up.

I'm thinking the cold start injector is leaking....Any other thoughts?
