What RPM should my engine be idling at after I start it? When my engine's idling, whether it's cold or warm, the whole truck vibrates, the windows rattle, etc. As soon as I take off with it, it quits, but it seems like anything under around 1000 RPM makes it shake like a wet dog. I took my boss, who's kind of refined and drives gassers, for a ride in it the other day, and he's like, what the heck's the deal? It was actually pretty cool, because with the vibrations and rattles and squeaks from the cowl cracks, and the slider being open to hear the exhaust, it kind of freaked him out.
I'm just wondering if I need to idle it up a little.
