Question about GMC Cars & Trucks
Driving down the highway, I got the warning lights and my vehicle started to sputter down the highway...I could only get up to 40mph after that and returned home.
Your best bet , take it to a qualified repair shop . Problem with electronic throttle control , do you know what that is ?
Could be sensor in gas pedal or throttle body , or wiring or computer or etc... etc.... Don't go by the problem this vehicle has ,could be a number of other thing's .

the engine light is a generic fault indicator in your car to point out something is not quite right with the engine, having a loss of power as well is also known in some areas as Limp Mode or Safety Mode. it means the car is restricting the power it gives to ensure no damage it done to the engine.
the only certain way to find out what is wrong is to take it to a garage that has diagnostics equipment that can read the fault codes from the vechicles ECU (the fault codes will be the reason the light on the dash has come on as its reporting a fault somewhere)..
your mechanic should be able to tell you what is wrong with the engine from that and give you a more accurate cost at fixing it.

I AM HAVING THE SAME PROBLEM BUT MINE ONLY COMES ON WHEN I AM IN GEAR, IDLEING AT A STOPLIGHT OR IN A DRIVE THRU. TOOK IT TO GM AND THEY ARE TELLING ME IT IS A "P0300 AND P0301" CODES WHICH SAYS IT A VALVE TRAIN MIS-FIRE ( TO FIX IT IS A 2000.00 HEAD JOB) AND THAT IS WHY THE STABILITRAK AND ENGINE LIGHT COMES ON!!! IN MY RESEARCH SO FAR I HAVE FOUND NOTHING THAT TIES THE TWO TOGETHER.
I HAVE 102,000 MILES ON MINE AND IT RUNS PERFECT AND MPG IS THE SAME AS THE DAY I GOT IT. I WILL KEEP YOU UP ON WHAT FURTHER I FIND. I AM NOW IN CONTACT WITH THE GM DISTRICT SUPERVISOR.
