O2 SENSORS

1994 Buick Century

Engine problem
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?

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!
