    I just installed a K&N air filter system and now my 99 Toyota Tacoma will start but then it dies right away... Any ideas?

    I was talked out of installing one of these in my truck by mechanic because apparently the oil used in the filter can mess with the MAF sensors...

    Guessing you pooched the sensor connection.

    Follow guidance from @TR4FTMFW and return the steaming pile for a refund

    Gotta agree most likely not seeing the MAF signal for what ever reason.

    So the ECM shuts down what it sees as a non running engine.

    OP just what code or codes have you pulled ??

    You had to have done something, left the sensor unplugged, or bumped another connection unplugged or something. Love or hate them a k&n intake kit ain't gonna cause a no start condition. Look over anything you may have touched during install and see if your missing a connection somewhere.

    K&N's are complete shit. put your paper filter back in, and change it on the recommended maintenance schedule.

    Guessing we may never know, 'cause he doesn't like the 'take it off' answer.

    It has to be faster, right? And more MPG? The ads say so.

    Usually oiled filters cause issues with vehicles equipped with MAF sensors.
    Toss the filter and replace it with an AEM Dryflow and you'll be good to go. The K&N intake is fine.

    The dieing sounds like you left the MAF unplugged or something of that nature. If you're new to vehicles, reinstall the factory intake and see if the problem has been resolved.

    I have never had single problem with my K&N. Cleaned it a couple times already and always monitor the MAF out of paranoia. The MAF still looks factory new and clean. I dont drench the filter when reapplying oil and let it sit a day before reinstalling.

    Another example why you should just leave these trucks the way Toyota built them.
