Idle problem My 1999 BMW 318i E46 has a idling problem at times, especially when cold. I've had the car by autoelectricians but it came back the same. When using the car the idling will go lower than 1000rpm and the car dies, after starting and reving it comes right. Can you help me.

I've had an Idling problem with my 1993 318i E36. First, I would suggest getting the fault codes for your car. There are places where you can have these codes scanned for free such as autoparts stores. The fault codes will tell you which components aren't working properly. Based on my fault codes, I replaced the Idle Control Valve, the oxygen sensor, the camshaft position sensor, and the air intake boot. I could easily install all of these parts in less than an hour. All of these replacements cost me a total of about $200 and solved the problem completely. Granted, I did this myself. Look forward to the dealer charging you over $500 if you have as many problems as I did.

The rubber after tge air filter have hole?
