I just installed a d16y8 into my 1997 civic hatch and now i am getting a hesitation at at low rpm or when i try to give it too much gas at one time .. car idols fine .. i am getting the secondary o2 sensor code .... i dont have one there wasnt a spot on the harness i got ... could this be causing my hesitation?

 

hey Takeoff... sorry i dont have any informative advice to give you.

but i was wondering.... how much did u purchase the engine and did it come with the tranny as well? Its cause i also have a hatch and i want to swap a Y8 in mine hood

 

BUMP for info, i have same problem with a d16z6, it lagggggs for a while before it kicks in at low rpm.. i have a cx tranny on it though, soo dunno?

 

same problem with my y8 the o2 sensor is connected on my header under the car i couldnt figure out what it plugged into but there is basically and extension cord that plugs the o2 sensor into the harness, the empty plug that you plug into should be to the right of your intake :/ hope that helps btw the reason it hesitates is because it doesnt know how much gas to give the motor so its basically drowning the bitch in gas

 

Sometimes it can be the O2 sensor that makes the motor run like crap. Sometimes it's a clogged catalytic converter that make the O2 snesor throw the code, clogged cat = runs like ****. How's your timing?

 

I have one o2 sensor installed but on the y8 harness there is only one o2 sensor the other o2 is on the harness that is in the dash which in my hatch doesnt have an o2 sensor there ... soo just the secondary o2 sensor is missing .. and i am running catless soo thats definatly not clogged
