THIS IS WHAT IT WILL DO WHEN I TAKE OFF FROM 1,000 RPM TO 4,000 RPM IT FEELS LIKE SOMETHING IS HOLDING THE CAR BACK BUT ONES IT GETS 4,000 RPM IT FEELS LIKE THE CAR HAS A EXTRA KICK IN AND FROM THERE ON THE IT FILLS GOOD ALL THE WAY TO 8,000 RPM THIS IS ON MY SETUP JDM B16 OBD0 SWAP IN MY 91 CIVIC SI NOW I ONLY HAVE ONE 02 SENSOR AND I KNOW THAT IS CODE 2 SHOULD I BUY A NEW ONE AND SEE WHAT HAPPENS

I HAVE A ONE WIRE 02 SENSOR FROM A 91 TEG LS SWAP CA I USE THAT ONE ON MY B16 SWAP IT ONE WIRE ALSO

 

This is what it will do. When I take off from 1,000 - 4,000 Rpm, it feels like something is holding the car back, but once it gets to 4,000 Rpm it feels like the car has an extra kick (Ironically, this is close to the time Vtec would be kicking in...~H8). Feels nice all the way to 8,000 Rpm.
My setup is a 1991 Civic SI, with a first gen JDM B16 (OBD0). I only have one oxygen sensor, and I know that code 2 is the O2 sensor. Should I buy a new one, and see if that fixes my problem?

I have a single wire sensor from a 91 Integra LS, would that work?


(I bet you'll get an answer now that people can read what you said without suffering a headache. You're welcome...)

 

well the 4000 rpm boost almost sounds like vtec but idk

 

O2 sensor.

It is running in closed loop and then kicks into open loop...open loop doesn't use the O2 signal for fuel mapping. Closed loop it looks are the O2 sensor and isn't seeing the correct reading, so it adds lots of fuel to be safe....

Get it wired correctly and it will be fine.

 

what kinda of ECU are you using, and is it a "STOCK" ECU?

 

IT A PR3 ECU WITH A LOCASH CHIP, Y DO U THINK ITS NOT WIRED RIGHT.

VTEC foo..... and you suposedly have it.

 

Chip ur ECU and disable the freaking POS 02.

where did you find that its an 02 sensor problem? I have the complete DTC list in front of me and no where do i find a code 2. only code 1 which is o2 sensor 1. So unless maybe a code two is the 2nd 02 sensor?
