Flashing Idiot Lights

While driving, the "Change Oil Soon" Light on my '91 deVille flashes, and the fuel data center cycles, resetting the average and instant fuel economy. It will do this a couple minutes and stop. The oil was changed about two weeks ago and I reset the oil life monitor

I need to learn how to reset the change oil light since the mechanics forget to do this when I get my oil changed.

On a Envoy you turn the key to run but don't start it. Then push and release the gas pedal 3 times within 5 seconds. The change engine oil light should blink for 5 seconds meaning you have reset the system. If it doesn't blink for you do the procedure again.

How do you reset the oil change light in 91 caddy devill

Disconnect the battery for 15 minutes and hook it back up that should reset any lights on the dash because it resets the computer. If the oil light stays on, you might have low oil or maybe even a faulty oil sending unit that is tell the computer there is no oil when there is oil.

2001 cheve venture (service engine soon) trouble light on

If ou fixed whatever happened during the oil change, the light will cycle off after about 3 drive cycles.

The check enine light just tells you that you are not meeting emissions right now. Only be concerned if it's flashing. That means you are sending unburned fuel to your catalytic converter whih will overheat and self destruct.

Look for a vacuum hose disconnected and check all the onnections to sensors such as, vehcile speed control sensor, mass air flow sensor, crankshaft position sensor, camshaft poition sensor, throttle position sensor, etc. Good luck.
