yep, the IACV has this effect when its not connected.

whats your full car & engine scenerio? just drop a motor in your car recently or wut ? need year & type of car info so we tech people can help you.

 

yea i just therw a motor to gether so i can have my car on the road but yea i just droped it in . my car wuse to be OBD2 but i had this motor and swaped out in jectors alt and distrbuter to make it compatible but yea i ther a CEL 14 its hooed up but i jaced the plug frun a OBD1 harnes and spliced it on the OBD2 harnnes ... i saw the OBD2 harness for the iac plug has 3 wires and the OBD1 has 2 wire pluge .. could it be possable i have the worng ones hooked up ....???

 

not a whole lot of help, because I dont know the name of the thing,
but after I did my swap I got a IAC code. I hooked the IAC plug up
to the black cylinder looking thing to the right of it on the IM. Messed
with the IAC, cleaning it and such a few times, couldnt figure it out,
the relized I had it hooked up wrong. Stupid mistake, easy to fix.

 

this also happened to me
but it turned out to be my fuel filter
go figure

 

well i switch 2 plugs around but then i trew 2 codes , the IAC code and the intake manifold temp sensor so that dident work , i guess ill do sum tril and error stuff with the plug since the harness on my OBD2 civic has 3 wires and the plug has 2 that i sliced on .....

 

did you mix up the plugs/wires?

ok, it sounds like you didn't completely perform the IACV fix. So you're car is OBD2 eh ? what exact year is it ? this matters because the IACV fix slightly differs between 96-98 & 99-01 civics.

For the meantime, if your car is between 96-98 check out this wiring diagram of mine here for the complete IACV fix:

or if you own a 99-01 civic check this diagram out:
