Since I bought my car I have been having problems with the car stumbling for a couple minutes once warm. The stumbling would only go away when I floored it or when the car fully warmed up. I replaced the usual things, plugs, wires, cap, rotor, afm cleaning, seafoam, ohmed the temp sensor, and checked for vacuum leaks. None of this solved the problem and the car would idle at 1100rpm once warm.
Today I replaced my oxygen sensor and the car runs much better, no stumbling or bogging. It idles at 950rpm and runs smoother in general. The rich fuel smell while driving is also gone. I recommend anybody who doesn't know if their's has been replaced to replace their's. I used a universal Bosch that came with the special connectors and it was very easy to replace. Total cost was $23.

Do you have any more info.......part number? where did you buy it ? is your car N/A or turbo ?

I have an 86 N/A. The part number I bought was Bosch 15725. Bosch says it is a direct replacement for the late N/A sensor. I bought mine off of ebay.
Here is the sensor on amazon. The connectors they include are very easy to use and look like they will do a great job of keeping water out.

Just be mindful y'all that I've read the threads can back out of the pipe, so pre-treat with PB Blaster and be-careful/have a plan if the threads come out too...

I soaked mine in PB blaster the night before and I couldnt get the sensor out, so I listened to clarks garage and drove the car around to get it nice and warm and the sensor came out rather easily.
