I have a 1990 and the brake lights are not lighting up when pushing the pedal. The Hazzard and blinkers work but all three do not come on when I push the brakes. I have pulled the switch and there is a capacitor on the connector that is broken on one side. I already ordered a new switch since...
sorry..... after replacement of the TPS and IAC still was stuttering and I found the the brand new MSD wires at one cylinder were touching the exhaust and melted a little. Put the original Delco on and it sings like an angel now.
