If your problems continue, you may want to bring it in to Tustin Hummer. Never been there myself -- but SoCal's infamous Hummer master mechanic Mike Sabarese just moved to Tustin Hummer from Cerritos. In the past, his help has been awesome to my H2's problems. Personally, if I have anything more serious than a bad idler or pitman, I'd drive all the way to Tustin just so that Mike can look at it. 2cents!
