Handykapper Posted January 2, 2012 Share Posted January 2, 2012 My 1999 Lexus RX300 CEL light had come on. Went to Autozone and it was throwing a P0171 code. I replaced the MAF sensor and also check around for vacuum leaks. Reset the CEL and started diving the car. The light came back on but I continued to drive the car in case it needed to go through a couple of drive cycles. Now after 2 weeks of driving the car the light remains on. Not sure what would be the next best step to take. Any ideas or suggestions would be appreciated. Quote Link to comment Share on other sites More sharing options...
