Question about 2004 Chevrolet TrailBlazer
This used to only happen if the ac or defrost was on. I changed spark plugs about 6 months ago!
Sounds like a bad wire, or at best a bad connection. Verify all of the conncetions, at both ends. Make sure you don't take more than one wire off at a time. If you connect the wrong wire to the wrong plug the car will run like a junk heap. A bad coil usually means no spark.

did you replace only one spark plug? that can cause issues because of differences in resistances between cylinders. also, did the map code stay off after replacing
