MikeyMagic117: Hey Nathan, is there a hose that comes out with the ICV? One video from Bad Auto had a hose attached to it when he pulled it out but other vids there is no hose. I'm replacing boots tomorrow so please let me know if you get see this. 👍

SpectreLX: Main idle valve issue symptoms:
- Floating RPM during heating
- Missfires on cold start during heating
- Transmission kicks between shifting

hanoy Martinez: Hey Nathan hope your doing well... I've watched a lot of your videos. I own an x5 3.0i 2006 it's in good shape but am having idle issues such as rough and also chk engine light on .when I read the codes there were (misfire) and( too lean) issues. Do you think I have to clean my idle valve and or what should I do?? Thanks in advance

81indside: Thanks for your tip

Elvin Novruzov: Hi Nathan, my e46 does this while i keep holding gas pedal steady at 1k rpm. I cleaned ICV, TB, replaced MAF, air filter, Fuel filter & pump, installed used DME but no difference. What can cause it?

gunplay shootfirst: Thank you for the video bro very helpful

Apostle Kiplon Taylor: Hey Nathan, where is this valve located on the E34 and is it the same as this one you just cleaned?

M Breckwoldt: E38. Iacv. Cost $235. Will try and clean. Getting code p505 and p301. 225000 miles

Project E60: Thank you for the video. Really helped a lot. 1 question, can I use throttle body cleaner? Since I have that laying around

Jay Sargent: once the icv is cleaned and re-installed , does it need to be reset? i removed/cleaned mine today along with spraying all of the electrical connectors and including the MAF and now my e39 m54 520i is running like a bag of nails. im wondering if ive trashed the MAF or theres a reset needed for the icv. great vids by the way, since my e39 has started giving me trouble your vids have been great for info/learning. cheers Nathan.

RNS TV: How about show us how to take it out dick head

Mike Norman: Hi love the videos. That is what I'm doing to my 99 528i and I started it. And give it gas and it goes like it's dieing but I let go the gas and it idols but it's still running rough if you could help I'm just not seeing the problem

Gerald Wongkyezeng: Good Nathan please I just wanted to know can this cause the EML to also come on.

Kevin Sampson: Hey Nathan, I've got an occasional idle problem on my Z4 2.5. Starts fine but idle jumps from 900 to 1200 rpm, if I shut it off and try a restart it is usually fine. Wondering if this maybe an ICV problem. attached a vid on what it is doing. https://www.youtube.com/watch?v=Y-hzMHISGvg

Luke Malhotra: My e39 seems to run rough at idle when cold. But afterwards, as the engine heats up, the rough idle goes away. Could this be the problem with my car?

john jay: @Nathan's DIY Garage I HAVE AN 1990 BMW E34 520i BUT IT HAS THE M20B20 ENGINE WITH A ZF GEARBOX AND A 4.44 DIFFERENTIAL! WICH MAKES IT ALMOST AS AN E30 FROM A TECHNICAL POINT OF VIEW! THIS IDLE CONTROL VALVE IS QUITE EXPENSIVE AT 200 EUROS HERE IN EUROPE! AFTER CLEANING IT ALONG WITH THE INTAKE MANIFOLD ,AND THAT DAMN EVEN MORE EXPENSIVE AIR FLOW METER(400 EUROS BRAND NEW),PLUS A NEW AIR FILTER MY E34 WAS RUNNING AMAZINGLY GOOD! A NEW SET OF SPARK PLUG WIRES AND THE THING JUST TAKES OFF IF PUSHED IN 1-ST GEAR IN COMPARISON WITH BEFORE STATE,UNLOVED AND NEGLECTED! AMAZING ENGINES AND CARS THESE E30 AND E34'S! I WILL BUY ANOTHER E34 535i IF GIVEN THE CHANCE!

armando R: Hi Nathan I was wondering if I could get some help with bmw 01 330i, is has lean codes and misfires on cold starts I’ve replaced the disa valve the idler control valve new plugs the pvc system I’ve checked for vacuum leaks I’ve exchanged the injectors that I got from pick and pull the only thing I haven’t replaced are the o2 sensors you think it could be those that all went wrong at the same time

Screww Googlle: Hi Nathan....I am a big fan and tell all of my BMW buddies to watch your stuff.
I have a question...Right now I am working on an 85 E30 318i and the ICV is like new and works when I hook 12volts directly to it...but the wire connector going to it only provided 11.5 volts or so... and it idles up and down....but if I hook 12 volts directly from the battery it runs and idles fine. Why is the connector only giving 11.5 volts to the ICV ?
Thanks Dude....you're the best !

sharon moore: Yeah!!! Thank u!!
