upon startup,still in park the idle rpm raises about 1000 rpm above normal,after a couple of minutes the idle settles down to normal.always figured it had something to do with whatever is acting like a choke,(throttle body injection)messing up,or maybe this is normal.cold or hot weather it has the same problem.i can drive around all day,get the engine temp. to normal range and stop at a light and the engine will try to runaway,have to hold the brakes harder.than it will calm down after a minute or so.when i go to park the truck the idle runs away again for a couple minutes before it settles down.i normally dont allow it to run after i park it because of the excess rpm and just shut it down.any help is appreciated.
