i hed that o2 bank 2 problem,i m shure you all heard my story.i chenged that o02 twice sins jun-august, evryhtink was fine sisns august, but i didn't drive on the hwy more then 50mph.
i went last night i did 55mph for about 2 minutes and CEL came back o2 BANK 2, AGAIN WHY WHY WHY? WTF?

 

Is that the only code?

I remember your original thread.

What was your exact code (this time)?

 

Its your cat. Replace the cat and this problem *should* go away. Also please learn how to type, and create comprehendable sentences.

 

I had a similar problem w/ my 99'. I replaced the O2 and a month later light came on. Replaced it again light came on again this time it lasted for about 3 months. I thought to myself, man you should only have to change this thing at the minimum once in the life of the car. I found out that changing the Knock Sensor fixed the problem. I hope this will help you, it solved my problem.Good Luck!!!

 

def look into changing your cat converter.

also... you are 34 years old.. go back to 5th grade english and learn how to spell please! it hurts to read that post...

 

damn.. that's a mean duck

 

But that Duck is on the money

 

 

ok smart *** i came to this county 15 years ago and never went to school so learn englesh the best i can on my oun .why dont u go to another country and try to learn new lenguege,half of u americans can't even spell and speak your own engesh praperly,may be my spelling is bed but at list i can speak 5 lengueges.

now back to the problem.
thank you for all your ideas,
my code is o2 bank 1 again and knock censor, my cat is fine, i chenged my knock about 4 years ago. do u think i should chenge it anyway to fix that problem,and should i chenge o2 again?
