It sounds like a Mass Air Flow sensor or a Throttle Position sensor.BUT you will have to get a scan and find out what the check engine light is all about and related engine codes to attempt to fix this. This would be my first step. Good luck

Turn ignition switch ON then OFF then depress and release gas pedal 5 times to reset the computer. Worked for me.
SOURCE: 04' GMC YUKON DENALI CHECK ENGINE LIGHT ON & RUNS FINE????
Go to an Advance or Auto Zone and ask them to read your fault codes. This is a service they will do for free in hopes of selling you a replacement part. You likely have a faulty sensor that is causing the light to come on. Good Luck! I hope this is very helpful!

Hi, I have the same problem, I'm sorry I can't help, but if you figure it out please let me know.
SOURCE: About a week ago, while driving my 2007 GMC Yukon
Never go to a dealer,go to a local shop
Make sure they know why your there
Be part of the process,get involved
Get into the repair bay, when they call you,
with something they found.
The Dealer never worked on the check light
issues,obviously,what a waste of talant, and no
help to you.
They didn't need to clean injectors or spray
throttle plate. You could do that on Saturday
