i installed my jdmb16 and hooked up the 2 o2 sensor...i had a surge, light hesitation at any rpm...any gear...i tried switchin the o2 sensor but didn't help...then i disconnected 1 o2 and i am now runnin only 1 o2 sensor...and it runs better....and i heard that each 02 sensor helps the flow of air and fuel for 2 cylinders....that might mean that i am running rich in 2 cyl. and lean in the other 2.? im plannin to put nitrous and i am wondering if it would be safe since im running only 1 o2sensor....thanks

 

no one knows? or havn't had the problem?

 

Get get o2's. I had the same problem with my B16a1. Your car will run in safety mode until you get it fixed. Are you running a stock header, or aftermarket ceramic/stainless? Where are they located? I ask this b/c after installing my DC Sports 4-2-1, I had to get new bungs welded to the top of the manifold where the 4 goes in to 2. The o2's weren't getting hot enough in the bottom, and wouldn't register correctly. Running one o2 will make it seem okay, but it will still be in safety mode cuz the ECU is like "WTF IS GOING ON MFER, FIX ME". GL.

alrite let me try to find me some o2 sensors

 

hmm..i got rid of one of the o2 sensors. and connected both wires into one o2 sensor..runs perfectly fine for me...

 

okay....i replaced both my o2 sensor and it still has the slight surge at light throttle...wat could be the problem?

 

by safety mode, could that mean that vtec might not work? I'm only running 1 o2 sensor (got a DC header too) and its running kinda messed, but the only code I'm getting is 21 (vtec solenoid), but all the wiring is right and the solenoid is fine. the car coughs every 10 mins on average, at any throttle/rpm/gear, so I dont know what's going on. you think it's o2 related?

 

does anyone know? or have this problem?

 

yeah, i'm about to blow up my car, mines done this since day one. honda musta put the o2 bungs up top to begin w/ for a reason, that's my next line of attack

 

I have the DC 4:1 header and I'm only using 1 O2 sensor, runs great. No problems, an occasional check engine light but it runs fine.

 

running a single o2 when i had my mugen headers and on my jdm itr headers. no check engine light but bad idle.

 

i know its meant to run 2 o2s... but when i use 2 of them i have a slight hesitation at light throttle....like its not gettin enough fuel....im thinkin it runs lean? with 2 o2s...wat can i do to fix this problem?

 

am i the only one with a jdm b16?
