What kind of engine does a Yukon Denali have?
I have a 1999 Yukon Denali with a 5.7 liter V8. For approx a month…. The engine starts nicely, and idles around 700-800 RPM, which I think is normal. But when you accelerate past 1000 RPM the engine “bogs” down and sputters, and sometimes backfires under the hood.
Can a Chevy C / K 1500 run at idle?
There is often a backfire or two when this happens. Pumping the gas does not help. I basically have to crawl through any intersection until it picks up a bit of speed from idle. The truck idles smoothly, and it runs fine once it’s above about 5-10mph or so. If moving at a picking up the speed.
What should the idle rate be on a 1997 GMC Truck?
Underdog, I don’t know the 1997 5.7, but 1000rpm sounds like a high idle, not where it should “bottom out”. A V8 should idle at 500rpm. GoNDown, did you recently disconnect your battery? After I left mine dead in the yard for a while and didn’t charge it, when I started it up it ran like you describe for a few days and then it was fine.

I think it was doing a crank relearn (I no longer remember why I came up with that theory, though).
How much does a GMC Yukon engine hesitate?
GMC Yukon Engine hesitates during acceleration Inspection costs $89 on average. It can be frustrating for any driver to expect certain acceleration from their vehicle only to find that the vehicle seems to be hesitant while speeding up.
