5143, Replaced o2 bank 1. now running too lean? p0171
Posted by ryan95eclipse, Dec-31-69 06:00 PM
Ok so my girlfriend bought this car about 4 months ago. 1998 eclipse gs 5spd. 108k for 1200 bucks. no rust. needs a o2 front bank 1 sensor and a clutch. Get a used o2 sensor off a sitting car and rewired it (universal crap) Reset the ECU and the car ran great for about 20 miles or so then it tried to stall, rpms dropped quickly and then raised quickly about 2-4 seconds later to normal idle and a CEL appears reading P0171 or System too lean.
Any opinions. Car runs great. idles fine. lots of power. Smells a bit sometimes like gas.But everything seems good besides this new issue.
Car is stock other then a hps short ram and header to custom exhuast.
o2 sensor came off a 98 gs as well that was replaced not that long ago.
