Question about 2003 Chevrolet TrailBlazer
Could be several issues,as you suggest.
Can not diagnose without the vehicle,would only be guessing
You could clean the MAF and Throttle Plate with the CRC MAF and CRC Throttle cleaners.
I would also replace any spark plugs, that have over 50,000 miles or three years on them.
Then your on to the idle control solenoid or Air Idle Contol if you have one
Then start diagnosing the code for the misfire. You have one and can not wish it be gone. So get to work. All this is something we all live with several times a year with todays technology,may be your first experience. You really need to study these issues and try to do yourself. Dealers don't seen to care to do much at all,as you can tell by the thousands of people on this site alone.
You always have a local repair shop. I have the greatest respect for all those folks but they have a long way to go to build customer comfidence.
