i have a 91 honda civic dx hatch with a jdm b16a...it has light hesitation at 2-3 rpm cruisin at light throttle....its not throwin no codes....

 

check spark plugs, rotor, cap, wires. make sure tbody moves freely. could be clutch chattering a lil bit on flywheel

 

bought brand new cap and rotor wires and plugs....tbody moves freely...any other ideas why its hesitatin?

 

if you are running the two O2 sensor setup, swap your O2 sensor wires around, mine did the same thing, Someone here posted that fix and it worked perfect, no hesitation now

yeah..did that too still didn't do any difference..i swaped the o2 sensor

 

Sorry, no reply but I have a question on swapping the two O2 sensor wires around. I'm having the same problem but my O2 sensors have different plugs. One green and one white. And they can't interchange.

 

my friend put another connector on mines...

 

cut, strip, and solder the wires

 

disconnect the green o2 connector....and it should go away....BUT, your CEL will go on sometimes due to the o2.....but the hesitation will cease

 

mine has what I would describe as a "cough" at 3k (I just got the b16 in too) when I'm crusing in 4th or 5th. My check engine light is on anyway because of the vtec solenoid, but it (the check engine light) flashes once at the cough, then everything is fine. I experienced something similar to this on my d16a6, I was wondering if it could maybe be the fuel filter? My o2 sensors are spliced together because I have the dc headers. Maybe this shoulda been a new topic...but it sounds sort of similar.

 

I thought the Pr3 ecu required 2 O2 sensors. I'll try it and re-post.

Thanks,
Hung

 

the pr3 and pw0 should require 2, but I'm saying that I'm only using one sensor and its wired so that it gives the readings like its both sensors. that is worded awfully, but you get what I'm saying.

 

when you talk about switch the o2 wires. do you switch the wires at the ecu, or at the O2 sensors themselves?

 

yea, I was wondering the same thing. Wouldn't it be easier to switch the wire at the ecu instead of cutting and soldering? Also what difference does the green plug one make that no one is using? If I wire both O2's into the white plug, would my check engine light go off?
