What could be the problem if a 2001 BMW E46 M3 stalls out in neutral when coming to a stop?

The car doesn't stall out over 5mph just when preparing to stop..%26amp; how much might it cost to fix that issue?What could be the problem if a 2001 BMW E46 M3 stalls out in neutral when coming to a stop?I found this online, it may be your problem, first time I've ever heard of it, but it fit your symptoms perfectly.



"Symptoms can include a dramatic drop in idle rpm, and stalling during cold weather starts or when coming to a stop. In addition, most cars will experience an overall performance degradation and uneven acceleration throughout the RPM range."



After reading this, now I wonder because I have even gone to the dealer about the uneven acceleration. He said there was no problem and attributed it to me moving to a higher altitude and losing quite a bit of horsepower, and not being used to it yet. I moved from 800 ft to 6000 ft and lost about 50 horsepower. Oh well.What could be the problem if a 2001 BMW E46 M3 stalls out in neutral when coming to a stop?
I can throw in my guess just like the others. It is something related to the fuel delivery system, most probably the idle air control valve. Or a vacuum/air leak. But definitely not an airflow meter problem (although it could set a fault for the actual problem).

But I hate guessing, for if you are a mechanic and you start guessing, you better be a very lucky guesser, otherwise your family will starve.

Have it scanned for free in any of the parts stores that do it as a service. Then update your question.

Or post your question to a tarot forum. It is as good as any.What could be the problem if a 2001 BMW E46 M3 stalls out in neutral when coming to a stop?I'm sure you're pushing the clutch all the way in, right? your service light should be on, and the car should be in fail-safe mode. motor problems with these cars are about impossible to work on if you're not a dealer with a fat computer. the problem could be crappy gas, clogged injectors, $200) an overdue valve adjustment ($1000), or a bad accesory pulley. ($2-300).What could be the problem if a 2001 BMW E46 M3 stalls out in neutral when coming to a stop?
Something to do with the fuel system.....Most common problem is a bad MAF sensor. Cost on an M3 is probaly a couple of hundred...im sure the part is the biggest expense.
