Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Default Bad Idle in Drive after Diablo Programmer

Guys,
2003 H2. Used the Diablo Programmer. Great gains, but idle sucks in gear at a stop light. Idle sometimes bounces from 300 to 500rpms. Also, the AC blows hot if I dont give a little gas at a stop getting it up to 1000rpms. Im in TEXAS... ITS FREAKING HOTT! lol.

Any suggestions on whats up? I also put it back to stock, disconnected the battery, and reconnected, and drove for about 80 miles... And still same issue. Damn Diablo!!!
