Alright i just replaced all of the o2 sensors and have a new cat put on and well i now have this code. I was trying to figure out where the best place to look first along the wires. Not sure being a 95 how primitive the system is but i just want it to be able to work properly since im not sure if it is altering how my engine is running. Here some pics of what she looks
Certain O2 sensors will throw codes like a Bosch are know for this and also the cat system can create it. Search the forum and you'll find tons of threads that resolve this problem.
