2006 Hummer H3 Q&A
2006 Hummer H3 Question: My 2006 Hummer H3 starts fine, boggs down, idles rough, then dies?
My Hummer will start right up and sound perfect for about 5 seconds, then bogg down, idle really rough, then die. It's very repeatable. It started when I filled up with gas at a local station, I was very near empty when I filled up. Is that just a coincident or could it be something to do with the fuel? Check engine light is on. - baileykb
Clean the throttle body.. you'll have to take the air intake apart. You can buy a throttle body cleaner, or just wipe it with a cloth for a quick fix.. But it definitely sounds like your throttle body is dirty. - Blackfix
