This is one video out of a couple that I show how to solve your BMW E36 Idle Problem. Is your BMW revving up and down and cant hold a proper idle at 1000RPMs when stopped? I am experiencing the same problem and going through my BMW air intake system and fixing any old worn out items. In this video I replace an idle air control tube that is attached to the ICV (idle control valve) and an intake boot.

Thanks for doing the video. I've owned a 1994 E36 with M50tu engine for 16 years so experienced erratic idle several times . The most common cause is the cracked hose you found. I clean the cracked end with 70% rubbing alcohol , let it dry 15 minutes then seal the cracks with 3M weatherstrip adhesive. After 30 minutes dry time wrap a one inch wide piece of gorilla brand duct tape around the end about 3-4 wraps then install and reclamp with a lined stainless steel hose clamp. Other causes in order are the other hose next to it falling off , carbon build-up where throttle flap touches throttle body ( use carb cleaner sparingly with rag to remove build-up), cracks underneath that L-shaped air boot , dirty ICV , failing 02 sensor, dirty/failing mass air flow device or oil seepage past failing o-rings under valve cover that interferes with high voltage transfer from coil pack to spark plug. Using fuel system cleaner in gas tank at every oil change seems to prolong idle surge interval. Loose or wrong gas cap or oil filler cap can affect idle quality too.

Thanks for this. I needed to find the location on our E36 as just glancing it looked buried. This is a very informative video.

Thanks for your awesome videos! I was having issues with the idle on my e36 and I had the exact same problems. ICV hose was cracked and ICV was dirty. Also that 90 degree throttle plate that's normally open is actually for traction control I found out. It's normally open but when the ACS+T kicks in, it will shut that valve to reduce RPMs.

I have a 97 Z3 with 2.8L engine. I had a hunting idle once at operating temp. The RPM would go from about 1500 to about 3000 by itself, over and over. I did find leaks in the intake boot and tube to the idle control valve and replaced those parts but again after a couple days of driving to work and back, it started that unsafe idle hunting again. I ran codes and found a PO116, coolant sensor fault. I replaced it and so far it has not given problems. Can this part create the crazy idle problem I was experiencing?

@TheCOWBOYRANCHER 3 жыл бұрын

My z3 m had the exact rough idle and it would shut down if I didn’t press the gas. Replacing the cracked icv hose was the solution. The only issue is that the car has the service engine soon and I need a tool to delete that and have it pass smog.

@cya3651 2 жыл бұрын

My fix on my E36 m3 idles above 2000 RPM. Rpm does not come down if you rev it. It’s bcuz The CCV crankcase that plugs into the intake manifold was loose so on my car. my suggestion is to check for all the vacuum lines and locations for leak.

First I’d like to say great video, and was wondering where you bought that hose cuz mine is cracked pretty bad, just wondering if you can direct me to a link, I’ve already changed the air cleaner intake hose which was totally mutilated, but I still have some pretty bad rough idle action so hopefully changing that damn hose fixes it.. btw I drive a 97 328i

What’s your idle at? Today while coming to a stop, my rpms started bouncing between 500 to 700 until I started to go, it’s never done that but it does have a bit of a shaky idle, not too noticeable. I did the digital tac on it today and it’s bouncing between 650 and 710 and it’s never a steady idle and would go down to 640 coming to a stop. No visible cracks but haven’t checked it thoroughly. Good video!

Problem: I just found this AFTER I replaced the Air intake boot and the hose. Instead of pulling the 'throttle valve'', I disconnected the throttle and cruse control cables....now when starting the engine I have WOT. 1998 E36 323iC. Can you help?? thanks

@AutOdometer 7 жыл бұрын

+El Patrone I have never seen this before maybe disconnect your battery and let the computer reset for about 15 minutes. Only disconnect the negative terminal. After 15mins reconnect and see if that helps. If not check the tension on your throttle and also check the throttle position sensor to see if it was knocked loose or anything looks out of order. There may be a travel nut that was accidentally hit and is keeping your throttle wide open.
