Just in the last few weeks while hunting and camping in Northern Nevada around 6,800 ft elevation and with colder temperatures I noticed my idle would be high in Park when the engine is warmed up and also it took a good 5-7 seconds of turning the engine over and adding little throttle to get it started. Mainly all this when the engine is warmed up. On cold morning starts it started up just fine and idle seemed ok. But once the engine was warmed up after some driving, the idle would be high around 1,200 rpm in park and again, starting the engine seemed like it would not light up unless I gave it a little gas. I'm back home now at lower elevation in Vegas and warmer temperatures and firs start is quick and normal. After about a week back, I noticed today the higher than normal idle in park after the engine was warmed up. I figured it might be a high-altitude and cold temperature problem. But so far now at lower altitude and after the engine is warmed up to running temperature, the idle is once again high in park. So far starting fine. Any ideas? There seems to be no vacuum leaks that trigger a engine check light so far.
