>not looking for leaks before buying parts

Plugged injectors, buy a decent fuel next time.

Op here

I'll check the vaccumes and injectors tomorrow, and if they doesn't work I'll take it in to the shop to get the O2 sensor looked at. Can't be arsed to do anything else today, been driving around town all damn day to trigger the check engine light and try to troubleshoot what's been going on.

Check if your fuel cap is well sealed, some cars don't like it when they leak air into the fuel tank

I got the same trouble code a few days ago. It's annoying because it could be a lot of things.

On the canyon there is a small rubber elbow that runs from the middle of the valve cover into the air box. If it's not attached it'll suck in unmetered air and eventually set a lean code.

Check it!

check your intake hose

its probably cracked af

Did you clear all the codes first, run it a while, then check again?

Codes often stay for a while even after it's fixed unless you reset it.
