Unlike some, my high idle works as soon as I start the truck. I wait, however, until the volt meter swings up past 14. This generally takes about 90 seconds (guessing here, I haven't actually timed it). This really isn't a problem for me now cuz the weather is cooperating. Temps in the morning are around 20 above so I don't mind standing around outside- no remote start yet. Besides, I prefer to let it run at the reg idle speed for a while before kicking it up. But it's no fun when it gets cold. It seems to me it would be fairly simple to put in a timer. Start the truck, go back into the house, and 2 minutes later it would automatically jump up to the high idle. I haven't messed with electronics in many years so I was wondering if anyone has done this yet? If so, would you please share? If not, I will eventually be sharing a parts list and pics. Getting lazy in my old age, hoping someone can save me a bit of time.
