For the denso you can pretty much get any 4 wire and then just call or e-mail denso and get the wire diagram for that piticular sensor and your good to go. Napa or auto value. Pretty much any plave will have one.
I’m willing to bet like most CA 180SXs the wires are broken going to the 02 sensor.
I have a 1993 240SX with 175000km on it. I have a K&N air filter. I was only getting around 400km per tank and replaced the fule filter and get just under 500km a tank. Now I repalce the fuel filter ever year.
Just got back from calgary. 290kms and used 32.688 L. I was probably going 125km/h on adverage.
none of you should be complaining out of the dodge truck ive been driving lately i get 400 km to a 90 litre tank.
