O2 Sensors...need help! OKay...the SES light came on in my 94 z28 a4...so i had the codes pulled and it said it was the o2 sensors..so i go and get 2 new ones...the one on the drivers side was a peice of cake...but the passenger side was a different story..could anybody give me some advice on how to get the passenger side sensor out easier...thanks alot guys.
What's the problem, just not turning when you put the wrench on it?
It's easiest when it's warm. Just don't burn your arms on the pipes.

Get it any any local parts store for $5 or so.
Spray it on, let it soak in and the O2 should come right out.

Drive the car and get the pipes warm. Spray with favorite lube (PB, WD40, ect) and let sit overnight. Repeat as required.
If that does not work, heat with a torch and melt candle wax into the threads. Let cool and it should break the sensor free.
These always seem to work for me. But we don't get the rust you guys back east do.

I don't remeber the O2 sensors being that difficult to get to (at least compared to some other items. Now you may only be able to get about 1/8 of a turn before you have to flip the wrench over for the next 1/8th of a turn.
