I have narrowed my idle problem down to possibly my IACV, and i got a resistance reading of 3.1 ohms. I want to know if someone on here with a b16 can help me by getting the resistance of there IACV so i can be 100% sure. Thanks in advance.

 

Why not look in the shop manual? I'm pretty sure it states in there what acceptable readings are allowed to be considered functional.

 

I'll try to add more information to this thread as I was trying to help the OP at another forum. He has a 91 Civic with a 88-91 JDM b16a swap running on a chrome chipped P28. It has a surging idle problem. The FITV, ECT sensor, and TPS appear to test fine. The 88-91 Civic manual says their stock IACV should have a resistance of 8-15 Ohms. The OP's IACV reads 3.1 Ohms. The problem is that we don't know whether the IACV on his B16a and that of 88-91 Civics have the same resistance specs. Does anyone know the answer?

 

i personally have run both D-Series and B-series IACV's on my LSV. no issues at all (untill it goes bad at one point or another). even now that i am fully converted to obd1, i am running an obd0 LS IACV on my 1st gen skunk2 manifold.

 

are you measuring between the iacv pins with the plug disconnected? it should be in that 8-15ohm range. my b16 iacv is at 13.1 ohms. what is the issue, CEL?

 

Got roaming idle. When i start it and leave it running without touching the gas pedal the idle will sit a 1k. The second i touch the gas pedal and it is fully warm the idle bounces 1k-1.5k and so i am trying to trouble shoot the reading to see if the iacv i got from the wrecking yard is bad to, and yes i was testing the iacv prongs not the plug. Also no there is no CEL.
