Replaced O2 sensors, car idles perfect....

I just got done installing two new Bosch Oxygen sensors in my 89 SC. I was getting a code 41 in continuous memory and sometime in KOER. The car would stumble slightly at idle and hesitate a little at part throttle.

After installing the new O2 sensors, the car idles almost flawlessly with only an occasional puff from the exhaust (I think that is probably normal though, she does have 233K miles on her)

I wanted to thank everyone for there input and advice.

Thanks again,

Phil
 
Couldn't really tell...

I only saw the typical higher RPM High boost, smoke that our cars make. My problems are pretty much my gas mileage and the idle quality totally sucked.

P.S. I will keep you updated on the progress I have...
