When I put the truck into park the idle gets really low, and all the lights in dash kinda dim until it brings itself back up to normal again. A few years back I had the thermostat housing replaced, and noticed that it would also cause a similar issue when I had the AC or the heat on. The AC or heat would also cause issues if you were just parked at a stop light, even in drive. I cleaned the throttle body which was pretty dirty, and the IAC as well. The cleaning has seemed to fix the issues with the heat, but it is still getting lower rpms when I put it into park. I know it sounds dumb, but its almost like the idle needs to be raised or something. This has the signs of a vacuum leak, but I am unsure of where to look. I do know the PCV valve was replaced as well. Its a one owner truck with 152k, and I do have all the records for work done, I just currently am at work. The trac is going in on Sunday to get tie rods and water pump done, but I would like to look at something myself, or suggest a place for the mechanic to look if its above basic mechanical skills.
Thanks,
