Hey everyone,

So I'm having an issue where my car is running lean on a warm start and coming to a stop. The car on a warm will run lean for the first 5-20 seconds, then become normal. And when coming to start, afrs will drop to 15.9-17 for like 2-4 seconds, then become normal again. Not sure what's happening.. curious if it could be fuel pump related or something else? Any help is appreciated!
