Gosh Dang O2 Sensors

Recommended Posts

Alright, so on my 2002 Firebird V6 my catalytic converter kicked the bucket. I took this as a opportunity to buy some straight pipes for the V6 and glasspacks. (I know, but if i want to v8 swap, the pipes will be there now anyway.) My question, since the O2 Sensor is AFTER the Converter, would i be able to just zip tie the sensor to the frame? What im saying is, will the car run without that O2 Sensor behind the cat?

It might run.....But not like it's supposed too.....Will be in a constant open loop...and will have the check engine light on...As the MAF sensor will and the oxygen sensors will not be talking to each other and will be in a constant cold start mode and running on the factory cold start parameters and at the very least....Will probably idle really crappy and run super rich....among several other issues......Would highly recommend putting a bung in the in the exhaust pipe and reinstalling the O2 sensor in the proper location.....Can always plug it off later......
