1994 Buick Century o2 sensors

1994 Buick Century 6 cyl Front Wheel Drive Automatic 145,00 miles
----------------------------------------------------------------
problem was with my car with stalling all the time and poor gas consumption. (3800) 02 sensor showed up on scanner w one-wire O2 sensor like it was called for-still stalled and check engine light was still on. Put in 4-wire sensor and it runs beautiful!!!!!!!!!! (front 02 sensor). What's up with that? I thought they didn't use them till 96-maybe my car is newer than I thoought?[/quote:9f62f8a37d]

how did you plug 4 wire sensor in one wire plug?????????????

That's a good question :) :!: I didn't do it-I will ask him. I t was running great for 2 weeks, but now I have another problem with it skipping (bucking) and serging forward. After the 02 sensor was put in-it ran beautiful-no stalling and no gas guzzling. I'm almost ready to give up. I just can't buy another car unlessI get this one right to sell it. Thank you!!!

Also, I was told that this is a california car so their emmisions stuff is different?
