Help!!!

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?

P1131 is referring to your o2 sensor upstream bank 1 and P1000 is OBDII Testing not complete, maybe because the O2 sensor failed.

The P1000 is actually as stated due to my battery lol. That shit is getting old though. 3rd car I've gotten that I had to buy a new battery for. And them sh!ts ain't cheap. So I need new 02 sensors like I thought huh? Would that cause the surging and stalling after warming up and being parked or stopping at a light? When cruising its fine.

Also any ideas on the clicking/ ticking noise? It gets louder in up to like 3000-3500rpms, then around 4-5000 it kind of fades out. I'll upload/ link the video now.

To be honest I don't know but it wouldn't hurt to try. They aren't that expensive but maybe also check to see if you have any vacuum leaks. Maybe a boot or something is cracked :idk:

Definately check for vaccuum leaks on some old and cracked hoses.

It is hard to tell in video, hearing a lot of sounds, I hear injectors mostly. Most times modulars get the ticking either from timing chain tensioners losing tension and the chain slaps the guides a little- about a $450 job to replace the whole set up right.

The other ticking problem, mostly prevelant on the 4V is the passenger side lifters. Cost about $7-12 a piece depending on where you shop. And you can replace all of them generaly with a screw driver. Just google it and you can find 1000 examples of replacement.

Just start small and eliminate all the easy fixes and typical reasons for the issue.

Thanks John. I'll try the spark plugs and vacuum leak first. The stalling I'm being told is due to a bad 02 sensor.
