    Dude, me too! I miss having my second battery set up, but I can reinstall it, this time will just put it in the cab. I'm really thankful for this forum; its a great way to learn what not to do and what to do, when you have the money and lack the common sense, or simply possess the overwhelming curiosity and a Tacoma

    Update! About 3 yrs ago, I bought a apparent Denso MAF off ebay $21 I think. i decided for the price, why bother cleaning. Just get a new one. I noticed in my research with my P0171 code, the part number on the one from ebay didn't match completely with the number the Toyota dealer had for their MAF. Dealers was
    $158 22204-21010 Internal Air Flow Meter
    22204-21010. The one I got from ebay
    $103 22204-22010 Intake Meter Sub-Assembly
    22204-22010 . I bought a used 22204-21010 off ebay. Got it today and installed. My long fuel trim now reads -5.5 at idle instead of -18 and goes to 0 around 1800 rpm. And when I punch the gas pedal, it no longer cuts out. I believe the 22204-22010 i got 3 yrs ago is a cheap knock off and the main reason for my p0171 code. So, be careful when your getting a good price on ebay for a denso part. Make sure the numbers match true OEM.
