Need Help...Codes
Need Help...Codes ok i have a 01 camaro z28....cars ses light came on, so i went to autozone...they told me it was the o2 sensor.........bought one new sensor and when i went to change it noticed that the car only had one o2 sensor in the front and none in the back...So, i replaced the one on there then had a bung welded in and put in another one up front,,,,so now i have two front o2 sensors but no rear o2 sensors, no cats either.........cleared the code and then several miles later its back on..........took it back to autozone and they told me it showed the codes p0160 then p0140...........What do i need to do to fix this car....they told me it was the front o2 sensor that was showing bad...is this correct?
