Ok I did the diagnotic of my ECU and I got 7 long 2 short. This means Threeway Catalyst Right Bank! What needs to be fixed? What I am thinking is an O2 sensor. Am I correct or can someone tell me what I need to fix?

It might be an o2 sensor but there are other more specific codes for a bad o2. How many miles are on the car and how well has it been maintained?

I have 84000 on my car and I keep up with maintaence. I do everything thing when it is needed.

Try just clearing the ECU and checking it again in a few days or weeks. Mine will throw a code every once in a while for no apparent reason but I have 120,000 miles so my sensors are probably questionable except for the knock which is new.

I have 120,000 miles so my sensors are probably questionable but after I clear the code everything seems fine usually for a long time. I haven't had a CEL in almost a year.
