Idle Issues

[atlanticbluem3]

Sorry but no,I am new the site and have a problem with my 98 M3.

Car is well maintained and has only done 70,000 klms.

First she has a problem with the idle . Drops down fast when you go to stop.Idles down to 500 rpm then goes up again. First time it happened it stalled then wouldn't start at all for a while. Has stopped again altogether again but did restart then. Any clues ?

Next thing,I need to replace the acc drive belt ,how do I un clip the radiator ?

Cheers

Your idle problem is related to your ICV, or Idle Control Valve. Try and do a search through these forums for an actual DIY.

The clips on the radiator are a bit tricky. I haven;t done it in a few months and it's really not in my memory. Every time I do it I basically just shimmy around and figure out the clips. It takes about 5 minutes but you will get it. Some sort of downward action angled towards the front of the car if I recall. Just give it a go. Large flathead recommended.


edit: luckily someone bumped the topic for you

That was my DIY... But I still notice the idle issues, even after performing the Idle Control Valve cleaning.

Interesting. Possibly new ICV is in need?

changed the title cuz lots of people use this section at work

also, if u see little change after cleaning the ICV, get a new one

if u see no change, its something else....

def sounds like ICV, but if you change it w/ no resolve, i might see if you can code the ECU and get a cam sensor error. Of course, if that was the case, the car would periodically idle/run rough too.
