Hey all, just purchased a 2003 Vibe with 288k miles. Going through it and fixing little things while tackling the larger issues of a P0420 code and no right turn signal blinky. As far as the P0420 I'm just waiting for the light to go out after applying the recommended fix (Upstream O2 Sensor). OBD2 scanner says it should pass... All the emissions passes in my scanner. It's the turn signals that are causing the most stress. I put a post in Electrical explaining the issue and what I've done. I'm just glad I found this forum, a tons of information here!
