A few days ago, I noticed my 98 328i idle lower than normal. Turn on the AC, dropped even further instead of being compensated for. So I got to the IDLE CONTROL VALVE, removed it and cleaned it out. Made a huge difference. Car definitley improved.

So this is just a little fix I can offer here. Don't always be in a hurry to replace things. Same thing goes for the throttle body: clean first!

It's not hard at all. It is right next to the oil dripstick. It is under the intake manifold which you do NOT have to remove. You remove the rubber boot form the air box to the throttle body. Then the two mount bolts for the throttle body. Just move the throttle body to the side and do not disconnect any wires.

This will give you room to work and you can see the ICV. The dripstick tube has one mount bolt. Next to the mount bolt are the 2 bolts for the ICV. Remove the two ICV mount bolts and pul the ICV straight down. Once it is free, you can disconnect the wire.

Spray the ICV with an alcohol based cleaner, such as the spray used for fuel injector and throttle body.

A quick way to locate the ICV is to follow the black hose which taps off the rubber boot after the air box.
