Having problems with your Chevrolet TrailBlazer ?
Rough idle in drive gear with vibration in 02 trailblazer
Hello my name is Israel and I will try to help you. If this just started and everything was working fine, my suggestion to you would be to first remove the tube from the air cleaner to the mass air flow. Once removed you will see a "butterfly" in there. This are will need to be cleaned with a cleaner easily bought at auto parts. Also use a screw driver to hold open the butterfly so that you can clean a little on the inside. It still may run a little rought for a few seconds but should clear up. Please let me know if this helps.
