Valentine Valentine Posted November 21, 2020 Share Posted November 21, 2020 Need help finding out why my car keeps having check engine light on. Everytime I reset the computer it's comes back on in about a day. It keeps saying I need bank 1 and 2 O2 sensors and bank one is running lean. I had replaced the O2 sensors 3 times. So now my car when I drive is sluggish when I press the gas until the RPMS reach around 4 rpms then the car takes off. I had the throttle body cleaned and the MAFS replaced and the car still acts this way. Even had the coil packs changed. Is anyone having this problem? Could it be the computer is bad? Need help.
