97 GMC Yukon check engine comes on when idiling

Hi, I'm having a problem with my check engine light coming on when I'm idiling. It flashes for a few seconds then stays on for a few hours. It always goes back off. It seems to run fine, I can't feel any shuttering or rough driving. Any suggestions?

When you turn the ignition ON before starting the car, the "Check engine" light is supposed to come on indicating that the engine computer (also could be called ECM, PCM, or ECU) is powered on. If the "Check engine" light does not come with the ignition ON, it's possible that there is no power coming to the engine computer (e.g., due to a broken wire, faulty main relay, burnt fuse, etc.) or that there is a problem with the engine computer itself.

The electrical harness between the steering column in these gmc units are troublesome. I just paid $500 (part $300) to have mine changed out on my 97 gmc yukon, but for 335,000 kilometers, no leaks, no oil consumption, not bad
