Engine idles erraticly in park only, It revs up and down, idles fine in drive and reverse but sometimes will buck at very low speed and rev high on shut down. When in drive it runs fine on the road. Code 171 system too lean comes up on scan. Could it be the idle control sensor or throttle position sensor?

No it is not a sensor. It is the air intake supply tube. Found a hole/crack on underside of tube, put my finger on it, idle evens out, nice and smooth. Tied shoprag around it temporarily until part arrives. It is running much better now with the temp. Band aid. Answering my own question because nobody really answers unless you pay, right?
