Hi I have 2005 GMC envoy. When I start accelerating from stop, the car hesitates. This doesn't happen all the time, usually when the car has been standing still for atleast a few seconds. Any help would be greatly appreciated.

The TB is clean on the backside? Just checking, because some folks just look at the front. But if you took it off to clean it, then no problem.

Change plugs at 100K miles / 160K Km?

I'd run a search here on Seafoam and treat the engine and intake manifold.

BTW, Welcome fellow Canadian to Trailvoy!! :tiphat

You've got an '05 with 175,000 km on it, wow, mainly hwy clicks I'm guessing? I've got an '04 with 122,000 km. At 100,000 I cleaned my throttle body, but only the front. Never thought about the backside.

Thanks everyone for the input! I cleaned the backside of the throttle body, now the problem seems to have disappeared.
