Ok here is the deal. I have a 94 cx with a b16a. I bought the car with the swap, and when it was put in, the person didnt rewire for the b16's 4 wire o2, which gives me a code 41. When i bought the car, and up to recently, the car ran fine.

Now, the car idles fine when cold, but completely ***** out when warm. The car has major bogging when driving warm, and almost stalls at idle (drops then jumps back up).

When it idles shitty, the car will make a light popping noise when the rpms drop.

cap/rotor/plugs are new, fuel pump is new.

So, basiclly what im asking is could the code 41 finally be causing problems, or is it something else.

 

anyone have an idea?

 

Well you know by wiring it up, you'll be fixing something, so it's certainly worth your time. Without an O2 sensor, the ecu is left a little blind, so it's not going to run very well. It's usually not that bad, but then again, it could be it.

 

yeah thats the next thing im going to do, but i just dont know why it would all of the sudden run like now, and not int he past. Oh well. Ill just throw some parts at it and hope
