Default No more trac light

I cleaned the throttle body and re adjusted the tps and its gone no more solid trac light.And the trac seems to work nicer it dont kill it as hard in the snow the car seems faster then before with the trac on but about the same with it off so no power gain but trac dont take as much power away now.

I should have taken pics of the carbon and ***** in there it was bad.

If you have a solid trac light jump e1 and tc in the diag. plug by the intake manifold and count the blinks.

to reset/clear codes turn key on with jumper in e1 and tc and depress brake 8 times in 3 seconds

this is for the 1990 model i have no clue on other years

hope this helps
