IACV is staying on and causing battery to die! WOW! GREMLINS

well i thought my dif fan controller was causing the problem running the fans longer than 2 minutes after engine is turned off. the other morning im detailing my engine in my shop with dead silence...i hear this electrical humming noise. I put my ear next to IACV and there it is...i immediately unplugged it and it went away. when i plugged it back up i hear a relay click and it didnt hum anymore

i havent had any problems till i installed this dif fan controller. everything is wired up correctly to temp sensor and fans come on like they should. when i shut car off yesterday i immediately pulled the plug on iacv closest to front of engine. the dif fan controller shut off too...wtf!

is the iacv bad or is a relay bad in fuse box, because egi relay is always clicking when voltage gets low. im about to yank everything out and go back with clutch fan.

do i need iacv anymore? i dont have a/c. does anyone make a blockoff plate anymore?

im not sure about removing the IACV, but i think that Tim (r34gtr) removed his air regulator and IACV and just cracked the throttle open and adjusted the TPS to compensate..im not 100% sure on the subject but i think thats what he did..

as for the fans, all i did with mine was wire a switch in the center console to turn mine on/off..really simple.

i wanted my fans to come on @ set temps. having fans on all the time does not allow motor to warm up properly. thats why i went with dif fan controller. as far as iacv having voltage still going to it with car off is another story

I ran my car for about 8 months w/o an IACV........ as the connector was broken. most people get them from j-land with broken connectors and never wire them up.

you can run them w/o them plugged for sure.

yeah it def runs without it plugged up, but once i plug it up it idles up like its supposed to do. i need to figure this out soon or get rid of dif fan controller and get a thermoswitch and forget about it.

you are talking about the AAC valve correct? (greenish/yellow connector?) if so, just unplug it and run without it. i haven't seen it really effect idle that much on my car anyway.

A clicking IACV valve with the key out suggests that there's a wiring or grounding problem with the engine harness. Check your ECCS relay. Either its bad, or something is causing it to trigger on when it shouldn't be.

weird...i never had any problems till i installed dif fan controller.the iacv is not clicking...the relay is clicking. the iacv has a electrical humming noise to it after you turn key off...it stops once you unplug it. when i plug it back the relay clicks for a few seconds than stops.

the dif controller prob caused my relay to take a s*** and i installed it correctly to diagram. im about to yank the pos out...it doesnt cut off after 2 mins anyway like it should...it stays on for 8-10 mins,
