Idle Trouble Now (update and info)

Yesterday I spent all day trying to get my O2 sensor out but couldn't. The only things I did were run the car, spray it with PB Blaster and unplug the O2 sensor. So basically you can say I did nothing mechanically to the car..... NOw the car is idling like crap. It seems to run fine and idle fine initially. After running it for a bit the idle fluctuates big time. The tach goes down to 0 and just before it stalls it shoots up to about 2000 and then back to where it should be. this happens repeatedly when standing still but the car drives without a problem. If I shut the car off and on again it goes back to runing fine. I drive away and when I stop it gets bad again. Did I inadvertently do something? The only thing I am thinking is the PB Blaster got into the O2 sensor and this is causing it to act this way. Any ideas?

Even if it did, it would burn off almost immediately. I suggest letting it be until you can change the O2 sensor properly. Perhaps check other potential problems in the meantime - vaccum connections, TPS, etc.

I used Kroil (I have no intrest in the co.) on the exhaust bolts, o2, and manifold bolts and the stuff works. All of the bolts/nuts came apart after about 30-1hr of soaking in the stuff. I have seen it used in the industrial plants as part of their maint. stuff.

disconnect the O2 and see if it goes away. There should be a rubber quick disconnect plug near the cruise control unit.

...that your O2 sensor is causing your car to have idle problems.
The plug for the O2 sensor on the n/a 8v cars is at the rear of the engine, held in by a clip. Its directly behind the last intaker runner. Not sure if its the same for the S model.

Ahh, I see now. It's not a pulsating idle, its just either "on" or "off".? In that case, yes I agree, disconnect the sensor, and see if it goes away. If it does, bad sensor. Alternatively, it could be the throttle switch. There is a check to see if it's good/adjusted correctly on www.tech-session.com

Could I have done somehting the the O2 sensor? The car was running fine before I started to change it.
I just let the car idle for a bit. Seemed to almost die once when I first started it then seemed to level off. I am thinking it only happens after I drive it a bit.
