Default 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.

is the car turbo'd? or are you using the factory header in which the o2 bung is too close to the engine to swap the WB for NB?

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.
