    Hi guys (and girls),

    Have installed a K&N FIPK and now the engine will not run. It start no problem, but cuts out after maybe a second or two, I have tried applying revs, no joy! It sounds as if it is running out of fuel (which, of course it is not) and this makes me think it has buggered the fuel / air mixture but, surely this should not happen, the engine should just run a little lean, right?

    Any help really appreciated as I kinda need my car running, quick like!

    Thanks in advance,

    Sean

    Okay - made some ground...if I cover the filter with a rag (thus restricting the air-flow), the car runs at high revs but, still dies ultimately! What's the chance that the intake system cannot inject enough fuel? For the record, it is the correct filter for my car - 100 %!

    Hope somebody knows a quick fix for this!

    Have fitted a few K&N on e46 330ci's and never had a problem. Could just possibly be your MAF or a vacuum leak?? Have you tried putting the standard filter back to see what happens? If it does do the same thing, then try the above. Oh and theres plenty of how-to's on the forum for checking relevant parts.

    Okay, with the MAF Sensor unplugged, the car runs - fine! Not good enough really, why should I have to disconnect the sensor? Will running the engine without the sensor (thus not guaranteeing the mixture is right) will detrimental to the engine?

    help please!

    Right, as the MAF is unplugged and it runs fine, this basically means the car is running on default settings. So it more than likely means you require a new MAF. See if you can borrow a known working MAF and try it. If car runs fine then you know it's your MAF that is faulty. You could try cleaning your mad with electrical Cleaner first which just might save you some money.
    If you have to buy new then make sure it is original item not copy part.
    You can run the car temporarily without MAF plugged in. Mixtures won't be correct!
