Default I fu☹️cked up

I was in the middle of taking my cats out and just putting a straight pipe in and somehow the o2 sensor wire got caught in the sawzall and ripped them out. Now my check engine light, ABS and parking brake light is on and stuck on. What do I do?

If your ABS and Brake lights are now on from chopping a wire, sounds like you cut the abs sensor wires as well. It's the sensor ontop of your rear diff that reads the ring gear for ABS and speedometer. If your speedo stopped working under 35mph, you cut those wires. You will have to trace and rewire them.

Not a big deal man, idk how long ago this was posted, hope you got it sorted out but otherwise just reconnect the wires and check all fuses in line with circuits you disrupted (might be alot by cutting just 4 wires)

mine was doing the same thing. Check for a coil or wire arcing out. I found cylinder 6 coil was junk my surge went away my economy came back it runs like brand new again
