Nobody can figure this out. O2 code comes up .repaced all four of them but still stays on . Now colder weather it goes out some days and runs way better . Also at 2000rpm giving a little gas it has a miss or shudder until I kick it down a gear . Hope someone has any kind of help because nobody in my area does .

 

What is the code number and description for the code that sets? An O2 heater code is not the same problem/fault as an O2 Low Voltage code.

What brand of O2 sensor was installed?

 

they used bosh on 3 of them then another brand that I don't remember for the 4th because they ran out

 

I have to get scanned again this week since I misplaced the paper with the codes on it .will post when I have them . Thank you for your reply
