Question about 2002 Chevrolet TrailBlazer
Do you have a check engine light on in your dash ?
It may be your throttle body is dirty. Run some SEA FOAM engine tune up in the gas when the tank is about 1/4 full, dump the whole can in, drive it for a while then let it sit. If rough idle continues you may have to pull throttle body and clean.
