I have a stock d16z6 it keeps randomly going really lean like 17 to 1 a lot this is the first time its ever done this I have a weapon r intake some cheap ebay ceramic header and I've swapped it from auto to manual still running the auto ecu all this has been done a while ago so I don't think it has anything to do with it any ideas what it could be? I already reset everything by taking off the battery please help its my dd

check for vacuum leaks. make sure the fuel pressure regulator is still good, not leaking or broken diaphragm inside. did you potentially get a bad tank of gas? is the timing too advanced? have you changed anything recently?

I'm gettin fuel and I didn't see any leaks I'm gonna check my injectors in a couple minutes. And I found my pcv was completely clogged could that be part of it? Other than that ignition timing has never been changed I always get my gas from same place and I haven't changed anything recently besides oil and fuel filter but I'm gettin plenty of fuel to the rail
