    need help asap just started today i have a 2002 tacoma double cab v6.
    heres the problem it will shift when driving up to like 50 and it will get to my lowest gear and kinda bogs while just driving. i try to get it to step to a higher gear and it vibrates and then hesitates to shift but does. also when i accelerate it feels like its cutting in and out of power when im on it? and check engin light came on like twice just flashing like 5 times only when i accelerated sometimes. so i got home just now and parked it and noticed its rummbles/vibrates when i push the gas fast but not when i do it slow.
    sry for the messy thread. just wanna get this figured out asap and start troubleshooting. thanks

    Sounds like a missing problem. I would change your plugs and wires. And maybe give it some seafoam to clean your injectors and valves.

    First of all, it shifts at 50 with your ECT on Normal. If you put it on Power, it will keep it in 3rd to about 55-65 (depending on your accel). This is a bit more acceptable for myself and many others.

    As for rough idling, start with the simple things first:
    -Clean your MAF
    -Seafoam your engine
    -Check/replace your spark plugs

    If that doesnt help, take it to the dealer

    I would also go get the code/CEL read at AutoZone. so you have a better idea of what it could be.

    It should still be stored in the ECU.

    It could be the wires. If there still factory with alot of miles on them. Or bad/clogged fuel filter, or a vacume line. Try seafoam and cleaning your MAF and Throttle body. There's alot it could be though. But get the code so we can narrow it down.

    ok i got the code checked and it said that all my cylinders are misfiring. so i dunno what to check it cant just be the plugs. its gotta be one sensor or something telling them to do that. anyone have any guesses or answers plz.
    im parking it until i find out whats up.

    The coils are fed by some little control box on the passenger side, on the wheelwell. Guessing if that box went bad it could cause all 3 coils to miss so all the plugs to miss.

    honestly wouldn't know how, except is has a removable wire connector on it, maybe you could find someone with another 1st gen and "borrow" his box for a test. other than that the toy dealer has better diag equipment but they'd probably charge a small fortune just to diag it.

    Popping sounds could be backfiring, meaning the timing is way off. That could go up the line all the way from the crank position sensor to the ECU (unlikely ECU). Might end up letting the dealer or a good garage take a peek.

    Then again where is Chris4X4 tonight?
