My check engine light came on a few days ago. I had just replaced my O2 sensors just 2 months ago. The guy at AutoZone says the error is either a bad fuel injector or the front o2 sensor. Should I replace the o2 again or (talk my wife into the URD kit with fuel injectors.)

 

Exactly what code(s) were displayed?

 

An add-on to this question: can an 02 sensor be cleaned? I replaced mine 1 1/2 years ago and I also have a check engine light again (the classic PO420 code which I am guessing sgirt has also). sgirt, I think it's pretty cool that you and your wife drive runners!

 

Ditto, need the actual code number(s).

O2 sensors can be cleaned, but not reliably and it is not really worth the effort.

 

The AutoZone guy didn't give me an error code. I will run it by them again and get the error code.

Thanks for the reply's. I will post later on the code.
