I have a 98 civic dx that had a LS swap done to it....trying to figure out my idle problem I found out that the IACV is not even plugged in, therefore ecu isn't controlling the idle. I don't have a connector off the harness that seems to fit. Is there a mod that has to be done for this to get connected.

help me out

thanks

 

someone has to have a ls swap...help me out

 

You say you can't find a plug that fits.. Are there any disconnected plugs under/behind the intake manifold? You want to look for a yellow w/ black striped and a blue w/yellow striped set of wires for the IACV if I remember correctly.

If the plug doesn't fit then simply go to the junk yard and find one that does, cut it and reconnect to the wires i mentioned above and plug it in.

 

Ya I have 2 loose plugs but both dont fit I think the person who did the swap used the civic harness. I might just pick up a ls harness and use what I need off it like u mentioned.

 

Do you have a three wire plug that looks like this?

y7's have a 3 wire, everything else is 2 wire...

 

mine idles the same way as your and i have the right plugs i cant figure out what the problem is. i tried cleaning the iacv and othher stuff the only thing i can think of now is a bad tps.. or high timing

 

Automatic Y8s are also 3 wire.

 

yaaaa boiii thats exactly what i needed..... thanks a lot man


you guys know of any other connectors that should have been modified or changed?


thanks

 

wonderful, his car is a dx that had a y7

 

actually do you guys know if I have to change the pins for a non vtec engine?

 

it has nothing to do with vtec. the y7s/auto y8s had a 3 wire iacv, everything else is 2 wire. theres a write up on here about it somewhere

 

Well right before step 1 it states: "if your a 96-98 non vtec or a/t civic owner...."


thats why im asking if the pin out has to be changed if I have a non vtec ls motor.

 

they mean if it comes stock without vtec, aka cx/dx/lx

 

ya my civic is a dx
