I'm looking for suggestion on how to rewire the check engine light on my 85 Jimmy. I sets a code for low TPS voltage and the closed throttle voltage is 1.5V tried replacing the ECM and still the same code. Looking for a delay timer to wire into the light circuit to pass a SMOG check. It runs fine and passes on tail pipe emissions. I'm just looking for a way to make the light come on for a couple of seconds and go off. It's a 350 with the Quadrajet with TPS and duty cycle solenoid.
