Help With Codes
Help With Codes Guys I need some help. A while back I installed long tubes, so I deleted my rear O2 sensors. My car is throwing p0158, p0160, and p0140 all for the rear o2 sensors. My car is also throwing codes for the front o2 sensors, p0135, and p0155. Does this indicate that my front o2 sensors are going bad? I installed o2 simulators on the rear o2 sensors but its still throwing codes for the rears. What do I do about the codes being thrown for the front o2's?

I would get the rear 02 problem fixed first. they may be related. it could even be picking up an exhaust leak if you have one. Are the front 02s reading lean, rich, slow response. ect? I would have someone tune out those rear 02s, or get them hooked up (you must have catalytic converters for this to work).
