You can get the o2 sensor from URD for under $100 (they are good too, not the crappy universal ones) URD Denso O2 sensors scroll down for the application guide. You probly only need to replace the front one, if thats whats wrong. Check the MAF also (clean it maybe?). Also did you make sure the spark plugs were gapped right?
