if it has close to or over 100,000 miles it probably needs new spark plugs and wires.

If you have original plugs on an '05 and decide to replace now, some serious sh1t about to happen. I've been on the 2nd set for 6yrs, now @91k miles. Not needed, just cheap and easy to replace, before they seize into the head.

Help me, i don’t know

ABS wheel speed sensor rear location on my hummer h2 2005

Rear, back part, behind, at the back. Left & Right. Go under at the rear, look at rear differential, then look left or right and follow the wiring harnesses to where they connect at the backing plate.
