Maybe check the spark timing, but on a '90 that's controlled by a crank sensor. That's down at the front pulley, and there's not much room for adjustment.
Also, the yellow wire business was the EZK sending nuisance signals to the check-engine light. I think they fixed that before '90 by reprogramming the EZK, but I'm not real sure about that. Anyway, that didn't cause high idle speed.
I'd sooner believe that the AIC is sticky or bad, or the base throttle valve adjustment is screwed up. Better yet, VACUUM LEAKS.
