· The power of beer
Okay, guys..I need some help. What should the 5.3 idle at after being at operating temp. I have an '01 Tahoe, stock motor with 60,000 miles on it. A few days ago, it wouldn't start very well after sitting for a while. It would turn over and run for a count of 10 or so then die. After I let it sit for a minute, it would start normal. I cleaned the throttle body and it is starting fine now, but it is idling at 450-500 rpm's. I can't remember if that is correct or not. It doesn't bog down when you stop at lights, but it just seems to be hardly running. Sorry for the long post, but I just need some input. Thanks.
