Just replaced Plenum Boot, Intake gaskets, Injector o-rings and Throttle body gasket..(One suggestion I have..Buy the Felpro Throttle Body Gasket..$3.00 versus $27.00 for the AC Delco one)..Car running pretty good now..Have'nt seen the P0171 and P0174 codes come back yet..Thank God..Ranger told me that the idle should be 650 ..The car has been idling at times at 625, 650 and 675..Its usually either one of those when i come to a stoplight..My question, Is there an Idle relearn procedure for my car? Also..Thanks everyone for all your help..:)
I wouldn't worry about it. 625 & 675 are close enough. It's not THAT critical.

You might try cleaning the IAC valve (Idle Air Control) - it sticks out the left (front) side of the throttlebody, held in by two screws or small bolts. Don't lose one. Use throttlebody cleaner and a couple of hobby pipe cleaners (fuzzy wire) to clean way into the bore and the top hat plunger. Oil the silicone O-ring before you slip it back in.
