Narrowband Reads Wrong
My narrowband has decided to stop reading rich. Ever.
it reads 14.7 a lot, and it reads lean a lot, but it never reads rich.
I know the car runs rich sometimes because I just switched to 460cc injectors from the stock 1.8 ones, and I started it once before I changed the req fuel. Still no rich reading. I also have played with settings to make it run really rich just to test the sensor, and still nothing.
Is the sensor dead, or is there a setting somewhere I accidentally changed that would cause this?
btw, I have an LC-1 but I can't find anybody to weld the bung into the stock exhaust without charging me an hour of labor, and I'm replacing the whole thing with a new exhaust soon anyway so I can't justify the expense.

I know, I'm not excited that it's narrowband either.
Nope, not turboed yet. Stock header. I tried to get the old sensor out to stick the WB in there for a couple weeks until I put the new exhaust but the old one is too stuck. I broke a borrowed O2 removal tool in my attempts, so I gave up. It didn't even pretend it was interested in budging.
Looks like I'm sensorless until I go FI and have the correct sensor, eh?
What confused me is that it would read alright for a while, but then it just stopped reading rich, ever. I've been tuning off and on so I didn't know if I just changed some setting somewhere without noticing that it killed the reading or something. Guess I won't worry about it too much then. I'm running pretty rich everywhere right now I think. The plugs are pretty black. I don't really want to change anything with no feedback though.
Ugh. I hate living in a place with no decent shops. Honestly. An hour to weld in a bung? I don't even care if it leaks a little, since the whole exhaust is shot and I'm ripping it out in 2 weeks anyway.

Thank you, but I think I won't bother. Between the shipping and the installation it's just more than I want to bother with. I ordered all the new exhaust pieces already it's just going to end up being a matter of when my friend can help me weld it all up.
