My car keeps stalling when in park, or stopping at a red light. I have codes P1131 and P1000. Car is also stalling out and idling very low before stalling out. Also has a slapping/ ticking or clicking like noise when driving, kind of sounds like squeaking when parked though. Quiets down in higher rpms though unless you stomp the throttle, then you hear it again. Any ideas? I'll upload a video too. P1000 I'm not worried about because I just bought and installed a new battery. Do I need new O2 sensors? Is that what P1131 is referring to?
