2003 Tahoe LT 5.3 4x4 230k miles. No CEL
If if it sits for several days, when I start it, it sounds like there was extra fuel in the cylinders or something because when it fires it sounds like an explosion of really high RPMs that first 1/2 second or so but then it runs normal. The longer it sits the worse it is. 5-6 or more days and it's really strong and feels like something will blow apart. I'm afraid what would happen if it sat for two weeks or more and I tried to start it.
It doesn't take any longer to start than usual. The cases I've read about are usually that the longer it sits the harder it is to start. This is fairly recent too, within the past few months and I've had the truck a year and a half.
