    Yes, manual everything...even mirrors...
    Everywhere I read people say .031” for Denso with the 3rz for coil pack + wires to plugs yet my FSM manual says .043”

    2000 is a weird year where CA emissions stuff changed, went to coil on cylinder, etc. lots of mix ups part # wise too I’ve ran into. My truck is a fed 2000 truck with coil packs + wires (1/4, 2/3)

    Those much well versed then me with plug specs and the 3rz please chime in.

    Happy Sunday!

    Hmmm

    Sorry, have answer with a story

    step daughter’s car(01 civic) no codes/running OK/valve cvr leak
    Might as well RR plugs
    Dude these plugs were WAY well worn and gap was over full 2mils!!!
    Yes ran better afterwards, but no “obvious” codes/hesitations/etc before

    I.E.
    (Know u keep up maintenance lineman)
    Would gap mid and be done .9 to 1.0

    that’s a MINIMUM amt…..on 25yr old, I don’t think she will mind!

    Not sure how old that page is that you shared but according to the current FSM available on TIS, it's reversed. This is for the 2000 Tacoma 2RZ-FE, 3RZ-FE. Attached PDF, see page 4.

    this is exactly why I asked lol. Apparently errors with the TSM are common…

    mine is literally a picture from my physical book I have for the year 2000

    I am seeing a common trend - non CA emissions 2000 and older = 2 coil packs = K16R-U with .031" gap with while 2000+ CA emissions/ 01+ fed (dual cats) with coil on cylinder =
