2000tahoe5.3
TYF Newbie
Hey guys, I have a 00 tahoe with a 5.3. My problem is when I start it up after sitting for a few hours, when I go to put it in gear and hit the throttle it stumbles. It also sounds like it is popping in the exhaust, like its lighting access fuel in the cats. Once its warm it doesn't stumble any more but it just doesn't seem to have the power I think it should have. I dont have a CEL on, or any codes of any kind. This has been going on for a while. Any insite on what to check would be great.
