2001 Acura CL S-Type rough idle when stopped / intermittent stalling while driving. Threw P0131 code. Replaced upstream and downstream sensors. Ran great for a week and now it's throwing P0135 code "O2 Sensor Circuit Low Voltage Bank 1 Sensor". Rough idle, trouble turning over, and stalling again. I'll clear the code, let it cool off and it drives great again. Any ideas?

 

What brand o2 sensor?

 

Key Life. Cheapie I bought off of Ebay. Think I need a Denso?

 

Our cars are particular on front o2 sensor. Get a denso.

 

Copy that.

 

UPDATE: Replaced with Denso sensors and no issues. Go Denso!

 

Good to hear!

 

This should be a sticky I tried Bosch and failed as gnuts probably remembers. I don't think I got any codes but the car ran worse.
There must be a lot of others.

 

Funny I was going to make a thread on this same issue. Last wknd I had the same issue, however did not know to get Denso. Ordering one today.
