Question about 1997 GMC Sierra
Nothing, It doesn't work like that, when your brake switch is mounted , correctly , your pedal has a bracket on it that pushes the switch plunger in so brake lights are off. when you push brake pedal in, to stop vehicle, the switch plunger (spring loaded) comes out to turn brake lights ON ! get it ? when you release pedal it pushes plunger in, to turn lights OFF !

Sounds like you have 2 problems here.?
The engine stuttering sounds more likely to be an air leak on your brake servo system, weakening the mixture, and this will give you a lumpy tick over.
As for the stop lights, No 1 check its not the fuse.
You need to confirm you are getting a live feed to the brake switch with a 12v test light.
If OK, bridge this connection and recheck your feeds at the stop light bulbs.

These particular year models have a bad habit of the circuit board going out on them one at a time. I would by a new one from the parts house and replace it not a very expensive item.

Testimonial: "Thanks. Guess I'll have to pry open the wallet and let the moths out."
SOURCE: tail light problem
carefuly test the socket that the light plugs into with a test light. I have seen alot of the newer pickups etc. that have the push in style lights have bad boards. cost like 19.00 at orielys. on the back of your tail lights when you take them off of the rig. do you have to unplug a wiring harness and take 2 screws out? and pull the black plastic peice out and the lights push in. that is the board i am talking about replacing. use the test light to check the plugend if it works that will tell you.

You probably already know this, however the GMC 2002 Yukon Denali uses the Wagner 3157 (or equivalent) dual element bulb. The running light uses one element whereas the brake & blinker share the other element that burns brighter.
Check to ensure the correct bulbs are being used. Then check all wire harness connections. Since the blinkers function, then it sounds like the connections are good.
It really sounds like there is a bulb issue, so check that first, then let us know the results.
