Default 02 sensor ?
I have a obd1 computer on a 97 camaro. I'm going to switch the o2 sensors. ARe they the same for all years, and if not, should I get 95 or 97 sensors?

OBD1 and OBD2 Sensors are different. 1's are rectangular, 2's are square.

unless you have a 97... then you have to check to find out what ones they used. My 97 has the 4 wire flat O2's up front

That's my problem though, is I converted to the obd1, but my car is still a 97. Wiring harness, etc...So, I'm confused as to which ones to use.

When you say flat, you mean where the wires connect to the actual sensor? They are either in line or square?

Both of my o2's work. I am NOW getting a code 16, low resolution error. That sucks. I have the delteq ignition system, but I still use the opti for the cam sensor, so I guess it can still be the opti?
