I had to change one a couple years ago. But this time the engine light isn't coming on. When I have to sit at a light it loads up when I take off. You can feel a vibration from the engine till I hit 2k. You can also smell raw gas when your behind it. But theres no gas leak. I think the bad sensor is making it run rich. Anyone other ideas or agreements?

 

Do you have any way to monitor the car with Freescan (laptop and cable)? That would most likely tell you what's going on.

 

No, I never bought the cable. What would indicate a bad o2 on there?
