I've finished my MPFI conversion but the idle is eratic. I unplugged the IACV and the idle dropped right down so i think i've found my problem. my question is which IACVs will work? any OBD0? or from what years/models? just want to make sure i get the right part.

 

anyone? i just don't want to go through the hassle of getting the wrong parts again.

 

what motor

 

it's the stock d15b2 but with the mpfi swap from a d16a6

 

should work fine. im using a d16z6 manifold and iacv and it works great also.

 

...i need to know which iacv i need. just as long as it's obd0 or is it specifically for the d16a6 or the d15b2?

 

you use the one for the manifold your using.. IE d16a6 manifold... d16a6 IACV.

 

when the IACV is unplugged and the idle drops is that good or bad? Also can a IACV be bad even if the computer is not throwing the code for it?
