2004 Envoy 4.2 Lack of power while warming up and..
And sometimes it stalls at idle. No "check engine light" so far. You tubed a dirty throttle body cleaning video and that will be performed.
This Envoy stays at our cabin most of the time and has 128k on the ticker.
Any common problems that we should look into? Recent new parts-battery-water pump- air filter etc..thats about it. I have no idea what the previous history is on this as we bought it with 117K on it 3 to 4 years ago. It has been running great until last week. thanks.
