    I too thought My maf was bad one time on my e36 328.. I bought a Chinese aftermarket one off eBay and the car died as soon as I started it.. cleaned the original maf with some maf cleaner and it was good again

    I was originally advised to clean the maf which i did with maf cleaner. Upon doing that the car started to cut off when idle for periods longer than 20 secs. I then decided to take it to a bmw service center this morning. The tech advised me to totally replace the maf which i did which brings me to the issue i have now. I replaced it myself bc i honestly didn't have the $1000 to have them do it

    Try your stock maf again now and let us know how it is. It would be worth taking your car in to a BMW specialist

    Disregard. According to the advanced auto part site, the bosch maf doesn't fit my car.

    Return that part, forget Advance Auto for all critical sensors.

    let's be careful of assumptions - that gets us in trouble.

    i'd follow marco's advice, and i'd also (as i already stated) look into your local chapter of BMW CCA - which is outstanding. especially if you intend to work on this car yourself.
    if all you are interested in is getting the car fixed and running (which is totally understood and reasonable - the fastest path is a quality diagnosis).

    my point is this - this is not a problem solved affordably by throwing parts. its hard for me to speculate (and that's all it would be) as to why the dealer recommended a MAF. keep in mind, you may have multiple problems and perhaps the MAF is one of them. we'd need to see data (live, running data) as well as other information before we can make a recommendation - there's just too many variables at play here. any recommendation we can make regarding actual parts or repair steps is just speculation.

    i would not operate the vehicle for long with the MAF unplugged - you can cause damage to other downstream (read: expensive) components.

    another piece of advice - FLAPs (friendly local auto parts stores) are not your friend for crucial engine sensors on a BMW. and, in reality, there's not many parts or things you want from FLAPs for a BMW. maybe washer fluid, that's about it!

    Advice taken regarding flaps. Gonna try recommended maf. Wish i could provide more physical evidence. Is there anything i can provide specifically that would assist you seeing my issue? The diagnostic i provided earlier came from a BMW service center/ dealership in Alexandria VA

    How thoroughly did you check the intake tract for tears? (Not discounting your efforts, just want to clarify). The intake tract boots are 2 pieces and some cracks happen in difficult to see spots.

    How is CCV system?
    With engine running, what happens when you open oil cap, in detail?

    Even though the MAF can be a real issue, I think it's a red herring here.

    Just checked for leaks with a mechanic. We just basically popped the hood with a flashlight in hand. Gotta look up how to check ccv on YouTube. As i mentioned, don't really have any mechanical experience or the $1400 on hand that the BMW service center wanted to charge me. I'll take the oil cap off and let you know what happens

    Ok,your posted photos(post#20)reveal BMW codes that provide clues.
    In the code memory list, it contains codes for misfires(both banks 1&2),
    pre-cat oxygen sensor faults(banks 1&2), fuel trims out of range(banks 1&2).
    That info, combined with mileage of over 255k miles, leads me to suspect deteriorated components.

    Let's start with confirming easy to find intake leaks,
    by removing items #1-#6 pictured in the diagram(photo).
    Once removed, carefully check for any hidden cracks in rubber intake boots and elbows.
    Squeezing of rubber easily reveals any hidden cracks. If any found, replace.
    Since no real fault with old MAF has been confirmed, replace intake with original MAF that was removed, if still available.
    If age of pre-cat O2 sensors is known to be 255k miles-replace, as the recommended replacement life is 100k miles.
    Ideally, the codes would have been cleared from memory, so after performing these steps, and completing a short drive cycle,
    you would re-scan for new codes, to see if any return-or not, to confirm a fix.

    Worked a 14 hour shift today but will check for leaks tomorrow. I returned the maf i bought from advance auto parts and reinstalled the original one i already had after cleaning it again with maf cleaner. With original maf sensor attached, car runs for a cpl of mins before dying out. Sometimes i hear an odd sound comin from the engine. Sounds like a knocking sound. Only hear it when the car is running idle.

    I'm not sure, try to tape it up temporarily and see if you notice a difference ?

    That looks like serious deterioration-Replace any cracked intake components!

    Well. It’s prior to the Maf so I’m gong to say sure replace it but not likely.
    It does probably speak volumes as to the condition of the rest of the hoses.
    We cant keep playing “could it be this?” My original thoughts still stand.

    I understand what you're saying "can't keep playing could it be this". I'm just asking questions bc i honestly don't know and unfortunately i don't have the funds ($1400) to get it repaired at a BMW service center. I respect you guys opinion (my uncle actually recommended this site to me) and that's y i listen to the answers you give. I highly appreciate everyone's responses, patience and assistance. Im not trying to waste anyone's time, I'm just asking questions. Better to ask than not to ask.

    have you checked into the place marco recommended? just so you know, it will likely be less expensive than the dealer. also, that's only one quote, from one shop, on one day.

    have you checked into the BMW club chapter? just so you know, most dealers offer discounts on parts and service if you are a club member.

    we still know very little about this car - please look at the thread in this forum which asks for basic info on the vehicle. keep in mind, at this point in their life most e46s will typically need 3-4k right off the bat just to get it running right.

    You are not wasting our time, do not worry.

    Do you have basic tools and some basic mechanical skill?

    I would disconnect and remove the filter box, to get a better look at the tubing nearer the engine. Take pics of those.
    This is something you can do for free.

    It's not as good a method as a smoke test, but a large vacuum leak is usually quite apparent.
