They told me it was: P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1. He also added that it occured in the low voltage position He said he would replace one for 175 for parts and 60 for labor, and would do both for 410 (saving 2nd labor charge) if I did them both at once. So, I have a few questions: 1. He said to replace both rear O2 sensors, should I? 2. What caused this, and how can I avoid it happening again? 3. Is his charge fair? Thank you ahead of time for your replies T-Red 1998.5 Contour SVT Mods: Foglight 'hack' Manual Antenna switch (Thanks for the idea Ryan Wood) 20% tint all around

Typical part cost is $65 - $70 (US). Only the top rear sensor needs to be replaced. Always check the connector and wiring condition, a short to ground can cause this code.
