Re: I start the car and it revs real high and then all is normal

Could be because of a drop in temperature, the cold air sensor tells the car it needs more of a boost to get going, or it could be first signs of your IAC (idle air controller) going.
On the old RRC you could take out from the intake plenum and try cleaning it with some carb cleaner, or replace it with a chevy astro van one, but not sure about the p38.
