i do not have the back o2 pluged in becausei guess it was never there i just found out and i don't not thow a code for the missing o2, and i am not tuned what gives.

 

um, what?

 

uhh im geussing you didnt have a rear O2 sensor on your cat is what your saying?
its located on the bottom right side of your cat...and the plug attaches to the firewall on the left side of the coolant tank

 

p01601 i think the code is. I get it everyday my O2 is dead. You will feel a huge difference in power actually when your O2 reads correctly.

 

"and i don't not thow a code for the missing o2, and i am not tuned what gives."

you dont not throw a code? so it is giving you a code? and the problem is.... your ECU is doing what its supposed to when the o2 sensor is not hooked up?

 

no no no, the rear 02 was never plug in to my knowledge, i was never under the car so i didn't know it wasn't. i was just wondering why it wasn't throwing a code for no o2 sensor, i have had the car two years now and i havenever had a code for it, the only reason i found out was i was puttin on my new 3" exhaust and found the sensor hole plugged and no sensor plugged in.
