mini-meturbodx

ok I bought a OBD2 To OBD1 coversion harness
from fabrik8 and put it in my car and just ran a dx ecm
just for now. BUT BUT my car throws code 14
air idle thinggy the sensor that the coolant runs through.

the idle jumps around between 500-2000
not erradic but slowly


if I push the gas to the floor the car boggs out
and at 6 grand it sputters really bad



please guys help me out
thanks Eric
ohh it is a 98 ex bubble intake manifold
with dx TB and dx sensors

you sound like you have a vacuum leak of some kind. look into the throttle body, you should see 2 holes for the idle air one on the bottom and one on the top. they are kinda to the left. put you finger over the bottom port. it should stop idling abnormally. if this is what happens it is a relatively easy fix. try this and shoot me a pm. or just hit me on aol im. i have run into this problem before.

yeah i had the same problem and you said you didnt know what it was! but i wasnt throwing a code for it.

i found this out when i was working on a 95 gsr

did you open the bleeder valve on the thermostat housing ??? sometimes air will get in the lines , this happens alot when you do a swap .... check that first and see what you come up with.

when i put my motor in i had the same problem, i have an integra,but heres what happened, on the obd1 harnesses the iac valve and someother sensor are the same plug and they fit each other, every other plug only plugs into the one its supposed to, but on this particular one they can be plugged into the wrong one, check that, cuase tucker told me to check it and that was the problem, i was about to replace the iac valve but didnt have to, the plugs are right next to each other so just swap them, it might help, ionno......

see the plug is a 3wire orange,yellow,blue
it runs fine when i have the stock obd2 ecu in it
but once I swap them and put the obd1 dx ecm it
screws all up.

I might just buy a stock motor and forget about it

sounds like you may have a disfunctional ecu

if you want to bring the car over i can check it out for you. i have a spare ecu you can try too. if your car has a vtec head on it then why are you using a p06 ecu? you should use a p28 ecu thats what i have in my 98 ex with an adapter harness

yo mike, see if you can figure out why my car was doing it while youve got it down there
