hey guys last night i finished my b16 swap into my 89 dx civic, it runs but has a idle of like 1400 at start up when its cold, also when driving and i let my foot off the gas it bucks REALLY bad like the whole car shakes, i dont have vtec wired up or any of the extra wires for b16, i am also currently running a b18 ecu
thanks in advance

 

Sound like a wiring or fuel problem. You can try to take the idle down by adjusting the throttle cable or the idle screw

 

by any chance do u think it could be a vacuum issue, because we were playing around with the vacuum lines and its better but still occasionally does it, also i think it might be fuel because sinse i have the b18 ecu its totally different and i also have 2 codes, o2 and eacv(might be idle prob?)
thanks for the help

 

you're runn a 1.6l engine w/ a 1.8l engines ecu man.. way too much fuel goin in. get yourself a pr3 quick.

 

no i have a pr3 ecu but i dont have vtec hooked up yet or any of the other b16 wires(4) hooked up so am just running it, would u recommend just dropping in the b16 one?

 

Hook up the wires, and drop in the pr3. Ryan

 

Yeah, its sending too much fuel. Hurry up and wire your car

 

haha yeah this thing is a freakn pig on gas now compared to my 1.5, lol, there is only one problem, i dont know how to do vtec and the others,

 

Do a search on here, its easy. And once you have the 02 sensors wired CORRECTLY, then you will see a surge in fuel economy. Ryan

 

yeah i hope so, i am getting wiring done tomorrow hopefully
