  1. whats up guys As some of us may know, that the trac off light on the sc400 (1993) usaully comes on when the check engine light comes on.\ my lights usaully don't come on until maybe 10 minutes after I start the car or when I am starting to drive up hills. When the light comes on, I get crazy stutters at around 2000 to 3000 rpm. It would smooth out after 3000rpm and turn normal again. When I turn off the car, everything would turn normal until next time. I just change the 2 o2 sensers on the car and check the ignition coils, they are both fine, now I am suspecting something is loose or a corrupted wire or something. Does anybody know the wiring diagram for the tracktion controll and where it meets the check engine light? B)
