Please do not anticipate this problem.

Rough Idle without the check engine light can be a multitude of things.

Same goes for the Check engine light without the rough idle.

Rough idle with check engine light? Then you are in the head replacement club.

If it happens it will get fixed.

If you dodged a bullet like me, you'll have enjoyed your time with your HUMMER and not have fretted over every mile.

Life is short, just drive it.


Thank you, even though the problem is bad for those with engines built prior to 287591, a rough idle with the idiot light, will not always indicate a bad cylinder head (reference the latest bulletin I will be posting in a few minutes). There are many items such as plugs, ignition coils, fuel, injectors, even a blocked air filter that can give the same symptoms and depending on the problem, the same codes.
However, like you say do not anticipate the problem. If it happens, it happens, and like I have said a few times, even if you are out in the middle of nowhere, you have at least a 95 percent chance of putting a few thousand miles on the engine after the light turns on and the idle turns rough. So, the majority will NOT be stranded in the middle of nowhere.
