1996 olds cutlas supreme, 3.1 L has trouble codes PO171 and PO300. Any Ideas?


The po300 is a misfire code.This means there is probably a plug,plug wire,ignition coil,or ignition module.Check the coil towers one at a time.These are know for corroding.If you find one that is corroded then replace the plug wire also.Po171 is a lean condition code.The po300 could be causing the po171.If you have not had a tune up Now would be a good time.Hope this helps.Good luck.
