Help Me Diagnose

Drove home my 60 miles from work today all on the interstate. Got to the off-ramp and was sitting at the light. The car sputtered at idle a few times and threw a code. It did this last week but I changed the plugs hoping it was just them all fouled and never changed from lack of upkeep by the previous owner. The code was for the 02 sensor bank 1. The thing I'm worried about with replacing the o2 is that its actually a fouled injector which is messing a mix up and somehow the system is blaming the o2. My last one did this but after changing the plugs it idled perfectly. This one still breaks up at idle though. Give me your input guys...

Thanks

hey man i had the exact same thing. Bank 1 sensor 1 is right there underneath by the exhaust and the easiest one to get to. I remember i would get to a light..it would sputter a bit, drop low in RPM and if i didnt give it some gas..it would die. I would always get the code and sometimes it would go away..i went ahead and just replaced it buying online through advanceautoparts.com they had a thing going on if u spend certain amount..u can get up to 40% off..saved me a bunch of money and easy to replace.

Why not replace the injector? I'm sure you can find someone parting out a T4R.

Thanks Tim, I'm just trying to get as much input as possible so I'm not blindly buying stuff trying to fix it. I'm not just doing the injector because it can be one thing or a mix of a bunch.
