problem with o2 sensor
My father in law has a 96 vette that has been having o2 sensor issues. He has had the sensor replaced about 6 times and after a bit, the warning light goes on again and he has it back in the shop. Has anyone had a similar issue with this vehicle or know of any fixes for it? His mechanic is at a loss now.

You need to specify what code is being set when the Check Engine lamp illuminates. There are four O2 sensors on a 96 and each one can set multiple codes.
Consider first a new mechanic because codes almost never indicate a part is bad, they simply identify a circuit where input is outside parameters the PCM expects to see.
Correct diagnosis requires following the diagnostic steps for the specific code in the Factory Service Manual. Codes for O2 sensors can be caused by fuel, ignition, wiring and connectors, mechanical problems or catalytic converter failure on a 96.
