So I put a exhaust on my car a while ago and never put my 2nd o2 sensor back on. I guess it is running really rich because of the black shit on my bumper. I plsiced the wires and it just keeps blowingfuses. Any suggestions

 

are the wires touching eachother? because that will short out and blow the fuse.

 

nope not at all. At first I thought alright I mixxed up the 2 black wires? Are they both grounds sence they are black?

 

the two black wires are for the heater, the white is the ground, and the green is the sensor

 

i just did the same to my car but put the 02 sensors back in spliced the wires so they would reach, but i keep running rich cuz no cat, any suggestions, its killin my gas mileage but more important the ecu keeps trying the change the fuel lean out, making the car hessitale acts like its gunna stall, really pisses me off, theres got to be a way to trick the ecu in thinkin there still a cat on the car any help?

 

so does it matter if I match them up by accident?

 

what do you mean?

so let me see if ive got this right, you got a universal o2 sensor and spliced into the harness? and what wires from the universal o2 sensor did you match up with the harness?

 

I got the stock o2 sensor. I am just making it longer, so it will reach the cat. I matched green to green , white ti white. I might be mixing up the black wires though becaue there are 2. Does it matter if they are mis matched? Maybe that is why my fuses are blowing?

 

oh ok. just check the wires again. the two black wires should have a different color stripe on them too, like black/yel or black/white. i would try to match them up just to eliminate that possibility its causing the fuse to blow out
