need help i have 89 crx si i put a obd0 ls motor in with obd1 intakemanifold trying to run a obd0 ecu and i keep getting a iacv code.

 

BUMP NEED HELP BAD

 

make sure the iacv is plugged in, if it is try using the one from your stock si, it should fit fine, the ls one might be bad

 

you can just clean it out too search and you will find tons on it.

 

bump still need help

 

i dont think u can use an obd1 iacv on an obd0 car...sensor is probably different between series....when the iacv went bad on my old b16 i put the one from my obd1 d15b7 on it...and it still threw a code...when i put a good one from an obd0b16 on it the code went away...it might not be the case but thats what happened with mine

 

you can use either, u sure u have the correct plug in it?

 

yes i know i have the right plug on it.

 

the iacv could be clogged...it usually doesnt throw a code when its clogged...idles bad though and may cut off when the motor is still cold....if ur sure that the plugs are on correctly u need to check ur wiring to make sure that there are no opens in the circuit...have u tried a known working one? the one u got may have gone bad
