take it in to a REPUTABLE GM tech he can fix you up fast and correctly. This is not always easy to find , a lot are just parts changers and crooks , but I will say a great tech is worth every penny ,as he is a mechanical doctor !
Dont be afraid to ask for certs when you go in for service too . If they are not proud to show them to you they are duds! And look for the GM certs ASE certs are easy peasy ,and any tradeschool kid with basics can pass them, A1-A8 are easy, its the advanced ones that are tougher L1 + .
I personally have an ASE Master tech cert. Big deal, its all the GM ones that really count. Most unfortunate for me is that there are no good GM dealers left in my area that I would care to work at , so I gave it up in 2008 and will never go back to working on vehicles again ,except my own , I much rather prefer to be a machinist , better money too

I know what you mean about the proper certification though. If I were paying somebody real money, I'd want them to know my vehicle...especially with some kind of vague electrical glitch.
There are no good dealers left anywhere, as near as I can tell. Around here the dealerships are owned by just a few guys, so you'll get the same owner for Dodge, GM, Mazda etc.. It leaves both their customers and employees with little choice. So much for competition.

Flashing CEL means its something that will affect driveability.
Thats just from my experience. I have bought diagnostic tools, readers, you name it, just so i can continue to work or at least troubleshoot on my own vehicles.
The fact that it cleared on its own probably points to an emissions system leak, they usually clear in a number of key cycles once the leak is fixed or if the intermittent leak stops then enough key cycles pass its gone, until it leaks again! Most sensors will set a permanent code. Sometimes an O2 sensor can set a code that will clear after passing diagnostics by the computer for X number of key cycles, but it wouldn't be as quick as what you described because it requires more than a few cycles of the computer going from open loop to closed loop on the O2 sensor. A weeks worth of driving usually would clear up an O2 code after replacing the sensor, but some makes/models set a permanent code that has to be cleared by scan tool.
Gas caps are a big reason for CEL's these days. It sucks, but such is life in the emissions age. The wife's car, a Dodge Caliber, had an emissions leak that drove me nuts. The leak detection pump was cracked and leaking. Ironic right?? The dealer had to smoke test it to find it. Thankfully under warranty.
