2005 chevy silverado 4.3 v6, past month when parked, the idle goes up and down, i let it warm up and still does it. It drives good but just when i put in in park the idling is terrible. I replaces iacv, oxygen sensors, tps. When i replaced all that and reset the computer everything seemed to be ok and then it started idling bad again today. What else can it be? its very frustrating. Someone said vaccuum leak, but where exactly should i check for that. Help much appreciated
