Hey guys this is my first post here, thought i would come here since it is specific to our trucks. My truck is a 1998 RCLB 2wd with the 5.7 vortec. I start it up and it does the "choke" idle for a few seconds and then drops down to the normal 650 which is all good. But recently it started to, after it has reached full operating temperature, as soon as I put it in park it goes up to 1200 rpm really quick but then settles down to 1000 rpm. Still too high and I wanna see if anyone here could help me out with this problem. Motor has 210,000 on it, all original. Out here in michigan it has been single digits with a negative wind chill if that helps anyone out. Truck has a CEL, but the code is P0442, which shouldn't have anything to do with it I would think. If anyone can help it would be much appreciated. Thanks!!!
