On a 94Z, the car is an OBD1 car and will only have 2 o2 sensors, one at each exhaust manifold.
In 96 and up, where the cars are controlled by the OBd2 PCM. you will have 4 o2 sensors, one at each exhaust manifold and one after each of the 2 cats.

Hope that helps,
Claude

 

that answered my question, thanks bro.

some 95 cars (cali cars) had OBDII just some FYI

 

thanks trey, but luckily, i'm in texas. cats? what cats...lmao

 

where was the car delivered to.

my car started out in texas and now its randomly scattered through the country

 

well, my car used to be a state trooper z28...or maybe an ss...cause it didnt have badges when i got it...she's been in tx all her life...

reason i asked about the 02 sensors is because of another thread where i was talkin about leaded gasoline and then i was told that they would mess up the 02 sensors....

trey, if ya dont sell the doors, i'd really like to buy that little power window/lock/mirror panel off ya... oh yeah, do ya still have the driver's side visor? is it a dark blue color? i want that too...

 

Nope


My car is a Cali Dual cat car but they still came with the OBD1 PCM and only 2 o2 sensors. (one at each exhaust manifold).

I bought the car in NJ but the previous owner bought it in Cali and when she moved to NJ, she had it shipped. Why the hell did she move from Cali to NJ has still got me puzzled.

But as far as I know the OBD2 PCM for F-Bodies started in 96. But most if not all 95 cars came with the obd2 STYLE connector to plug hook up your diagnostic tool or Hypercrap.
