Engine Light for a few seconds on a full tank of gas?

[93 Freshcort]

This has happened a few times in the last couple of weeks, but after filling my tank with gas my "Check Engine" light will come on but only for a few seconds and then it goes back off again. Anyone have any idea's?? Thanks

Given the symptoms you give but no codes, I would guess something about the EVAP system is getting flacky.

Could be just the gas cap.

But before buying a new one, I would look all the hoses in the engine compartment that go from the engine intake manifold, thru a valve and a sensor, thru the carbon cannister, and back to the hose/tube connection at the firewall (that leads back to the tank). You will likely find cracks and holes throughout this hose, as it is not a very durable material.

Hopefully you have not already sucked debris into the valve or the flow sensor.

You'll probably have to remove air filter cannister to get to this area.
