  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)

  2. whats up guys

    just bought my 93 sc400 a month ago,

    recently I have been experiencing slight chokes

    or hestation at around 20mph becoming more obviouse

    and obviouse. Last week freaked out when I saw

    my CAT smoking hot after a 2 hours driving at constant 80s

    Does anyone else also have this problem?

    what might have caused this? coil? sensers?

    I like to start by checking out the plugsmyself

    but have no knowledge of the car..

    How do I get to it,

    and if I need to change it, what is recommended? :geek:
