    Hey Everybody, Just now joined ya'll so hope everyone is staying healthy. Ok, now to my issue. My lovely truck has decided to be onery and has started this surging issue when I accelerate like picking up to speed on a hwy. Anyway I did some Googling and there wasn't a whole lot out there but this is what I've done so far. Cleaned throttle body and cleaned air filter, I've changed the MAF sensor, changed the PCV valve (dirty) and now I'm going to change the MAP sensor if I can find it.
    #1 There's part of my question, where is it located on my truck engine? I'm assuming being that it's associated with the manifold but I can't find it.
    #2, have anyone out had this issue and what did you do to fix? Thanks ahead for your response(s).

    Richrt

    I dont think we have MAP sensors; not that I've heard anyways. Sounds like you might have a vacuum leak somewhere. I'd check all the little hoses around/on top of the intake.

    Thanks for the response. I purchased a MAP sensor on EBAY Auto and it referenced the part to my truck model and such as a direct replacement. Any one out there knows if this MAP sensor is a valid part for a 2005 Toyota Tundra Limited 4.7 V8?

    There is a reference to factory map sensor on the dealer diagrams. But in 20years there is no history of of faulty ones. And its not on every 2uz-fe. I Dont trust ebay or Amazon parts much. wondering why you want to replace it if you cant find it to verify it works or know if there is one on your teuck.

    Rockauto lists a few MAP sensors for 2005 models but I don't think our truck actually have one. My Google fu is not showing me where its located.

    You have a crazy 05. So on top all the things that could possibly cause surging you also have sai changing your air values and an extra 100 parts. puzzle.

    The only reason I decided to randomly change parts is 1) they are pretty cheap and if it fixes this problem I got by cheap other than taking it to our local rip off dealership and 2) I got by cheap. Now for the rest of the story: My original thread stated the actions I've all ready tried but I guess I didn't give the computer time to reset this air ratio value thing and now my truck isn't doing this surging thing anymore. Keeping my fingers crossed. So thanks to all for your response(s)and stay healthly!
