hello again. just wanted to thank everyone for their input. without a doubt in my mind this car was not taken care prior to me owning it. weather it was beat on or just poorly maintained, i cant believe its previous owner did not know this car was going downhill

i just got my car back from the shop today. along with the cv shaft, i did decide to have them track down the source of my p0171 code. it turns out the upper intake plenum had a hole melted through it right above the egr port. the exhaust pressure tested nearly perfect so their only guess was the previous owner let the catylic converter get WAAY to bad before having it replaced.
anyone ever hear of that happening? the guy said that it is common for that part to go bad, but not in the way mine did.

so yeah...... HOPEFULLY i do have a nice new pontiac now that will last me for a long long time.
