Hey I had my car tested and it said it has an upflow O2 sensors were bad. Only bought one like a dummy forgetting I have two. I replaced the stock sensors with a Denso Sensor. Cleared the computer but now its drinking more gas. I will replace the other sensor but is that the problem or are Densos bad and I need to go stock?

 

Denso's are quality, see:

Check your MAF wires to ensure they are clean... Ensure the O2 wiring & plugs are good as well.

 

could also be injectors.. gunna send mine in to flowtest n clean.

 

Thanks fellas. I'm going to check those wires and injectors while installing another sensor. My fuel meter is on the fritz too and I dont want to send it in. Cost a butt load.
