O2 Sensor Replacement
I need to replace the O2 sensor on my 85. Prices range from $25.00 (PEP Boys), $39.00 + shipping (Eckler's) to $52.81 (Chevy Dealer) for the part plus about $66.00 installation. Question how easy it for me to install? Also what is a Code 8 Engine and is there anything significant in the spec when ordering the O2 sensor other than 1985 Vette not a California car?

Re: O2 Sensor Replacement (hillb)
8 is the character in your VIN that says you have an L98 engine. This is a SIMPLE job for you to do. Rent an oxygen sensor socket at autozone for $15 and get your $15 back when done. Drive the car up on some ramps, remove the old, install the new. I have the Bosch sensor from Pepboys.

Mine cost $25-30 when I installed it just pulled it up on some ramps took the old one out and installed the new one. Never used the o2 sensor socket just a wrench. Now the car runs fine that fixed my problem. :D

I did mine cold but if you cant get the old one out when it is cold you can run it for a min. get the exhaust manifold hot to loosen it up a bit

Re: O2 Sensor Replacement (Goody)
O2 sensor was $26.99 for a Bosch Premium one at AutoZone. I had to get the special socket for another $8 as I have headers, still cheaper than any other option! Cost me $33 total and took longer to get the car in the air than it did to change it.

Re: O2 Sensor Replacement (oldace84)
I've owned cars where the O2 sensor lasted well over 100K miles, and others that needed replacement every 40-60K. That's a big range, but our vettes shouln't be different from the typical car. I suspect (but can't provide proof) that the better brands (Delco, Bosch) last longer than the no-name cheapies.
With a scanning tool you can look at the O2 sensor response, which tells you if it's going lazy (their response gets sluggish). When they crap out-it's obvious.

Re: O2 Sensor Replacement (sraft)
Sensors can age and it may be a little more difficult detecting a weak O2 sensor with OBD1 (On Board Diagnostics Version One)vs OBD II>
If you have some extra money, time, and like changing parts, around 50K miles, some suggest you would be wise to change out O2 sensors. Very subjective. Have driven some over 155K and never looked back. Changed out the vettes when changing exhaust pieces. Just depends.
Good luck all.

Re: O2 Sensor Replacement (Chris O')
Do a search in the archives for this one. Someone just did a great write up on how to test your O2 sensors.
The basics, are that you put a multimeter to the o2 sensor and then watch the response. The numbers should fluctuate rapidly. If not, you have a problem. The sensors are cheap enough, and easy enough to replace, that it couldn't hurt to just swap them out.
