Got a 1997 DX hatch and im puttin in a JDM b16a(obd2)
Okay so everything is wired up...So we fired it up and it fired up, but it wont idle....What am i missing that will make my car idle....Any IDEAS?

posHonda

so it dies right after you start it?

UGLYEK

yes...the engine will not idle, only runs when you give it gas. i don't know if i have the idle air control valve wired correctly

Pull some codes off it. It might be your map senor. Is it a wall mount or a throttle mounted? I had the same problum. I changed my map sensor and I wired the idle wrong. See if you mixed up the thermostat plug with the other.

UGLYEK

see thats what we thought cuz the map sensor and the thermostat or whatever are the same plugs...but i think we have it right cuz the map sensor is the longer of the two connectors....but could it be that i only have one o2 sensor hooked up.....cuz i dont have a converter or exhaust on it yet...so could the o2 sensor be doing that?

MatterMatt

I think he would be more likely to mix up the IACV and TPS plugs.

UGLYEK

cuz isnt the only thing that should mess up the idle is the iacv?... Cuz the stock wire harness has 3 wires to the iacv connector, but the b16 iacv plug only has 2 pins...So whats up with that?

MatterMatt

Make sure you have the IACV wired correctly for the 3 pin to 2 connection. I could swear there is a thread somewhere on that, maybe in the FAQs? If you don't have it wired right it would definitely cause you some problems. Once you have the wiring right, pull of the IACV and give it a good cleaning with some brake cleaner (never hurts). No, the IACV is not the only thing that would affect the idle(although a dirty, plugged, or broken one would). It could be a bad FPR, cam timing, vacuum leak, etc.

try getting A NEW HARNESS iether from an ex v tec civic or just an si. that would make things a whole lot easyer. with the ex v tec harness you just have to lenthen some wires and thats it. oh and wire the knock sensor.

UGLYEK

but i mean with this harness the only difference is the vtec and we have that wired up already....and we havent wired up a knock sensor...what is that?....and could it be that my throtte cable isnt tight tight...cuz there might be some slack in the cable......idk ....

jonezen1

did u pull any trouble codes off it?

UGLYEK

Nope....not at all...atleast not yet...

jonezen1

Pull codes off the ecu and see what you get

UGLYEK
