    Hey guys,

    I'm normally an avid lurker here and around customtacos. I normally just read and learn and always search and normally find my answers but not this time. I have found myself in a bind and don't know how else to solve my problems so here goes nothing:

    2001 Tacoma 2.4L 5spd ~175,000

    My truck is skipping. Specifically on cylinder 3. It did the exact same thing about 6 months ago and I fixed it.

    So it should be an easy fix right? Well not this time.

    - changed all the plugs six months ago but changed the 3rd one today again.
    - also six months ago I changed the ignition coil on 3. Fixed it then. Well I spent another $80 on a new one today and it still didn't fix it.
    - so I pulled the fuel rail and injectors and cleaned them. Nope.
    - checked all my hoses and connections. They're all good.
    - also just put a fuel filter on a few months ago.

    Still not fixed. The only thing I haven't done is a compression test. There's no oil on the spark plugs and my valve cover isn't leaking. No white smoke, so no head gasket. Good coolant level and flow, and no overheating. I need to change my oil but its just now time. I know all that doesn't really matter but I'm checking off a list for you guys.

    Before I did all the today I had advanced check it and it said misfire on 3. The lady told me to take it to someone with a better system so I took it to a local mechanic who has one of those $20,000 Snap-On computers and all it said was misfire on 3. He told me to change the coil and plug and as a last resort clean the injectors.

    Any ideas? Before I lose my mind and I blow my savings on a 2JZE swap :devil:

    I'd replace the #3 injector, before giving up on it.

    I had considered it. Any way to check it before I spend the money? And I'm not anywhere near the giving up point. The motor will have to split in half and fall out before I swap another in.

    swap the injector from number 3 with number 1 and see if the problem moves to number one.

    I forgot to mention that it doesn't skip until it is warmed up!

    Burnt valve. Do a compression check when warm to confirm.

    I'll do a compression test in the morning and switch up the injectors!

    might have to.




    This ^^ . Compression test, vacuum gauge, leak down test, or lab scope (snap on scan tool) will help finding this type of problem.

    Good luck
