    04 v6 loosing power going up hills. It hesitates over and over until I turn the overdrive off. It got worse on last weeks trip to central Oregon. It was even doing it with overdrive off for a while there. Its been worst at 1700 rpms / 50-60mph. But in central ore became worse then that.
    Just took it to my tire shop for tires (cooper discover AT3) and brakes. On my way I couldn't get it to hesitate. They drove it and can't find the problem... can't get it to show symptoms of it either.

    Anyone have thoughts?

    Mine did that a lot until I put the deckplate mod in. Seems to know when to shift a lot better now and will stay in the proper gear for inclines. And we have a lot of those up here :D

    Have you done a basic tune up? Plugs, wires, fuel filter, air filter?

    At 80k I bought from the toyota stealer /dealer and they did all the 100k maintenance. I now have 100k on it. So its been that long since any tune up work. Just synthetic oil changes and a couple injector cleaners.

    So what should I check out first? Fuel filter??

    As far as taking it easier on the hills and slowing down... this truck was seriously running like s! Im not riding it hard and we are not talking big hills. And I wouldnt say it feels like its hunting for gears. It doesn't go back and forth or even feel like its ready yo shift when it does it.

    Fuel filter.

    Are you running a K&N air filter perchance? (Or any oiled air filter)

    I think I know what is causing your problem....



    You are a Duck fan :annoyed:

    But in all seriousness, I would recommend the suggested tune-up above. I was going to say you have to remember these trucks only have 190 hp, but you say they aren't huge hills...so I'm not really sure. Hope you figure it out though.

    No k&n or oiled. Its oem with deck plate. I may only have time to do a few tune up items before another trip. Sounds like I should start with the fuel filter.

    As far as the hills and the 190hp go.. I have driven these same hills in the same truck before. Power totally cut off for a moment over and over. It felt really odd to me.

    I never tried just screwing in the deck plate. But I have had the mod for about 5the months so I would be surprised if it was related.

    Just a thought here. Any time my truck ran like crap I was either in the Pendleton area or central Oregon. Is there a possibility that due to the higher elevation that a sensor may be causing it to miss? Fyi no check engine light has popped up.

    Truck is still getting the tires on it so I havnt replaced the fuel filter. But I was thinking if its fuel filter why would it run fine after my long trip... ?

    The problem turned out to be a spark plug cable that went bad. It wouldn't stay connected to the plug.
