    anybody figure out what it is? 1gr engine with 25,000 miles
    hear this damn thing under acceleration, especially loud when driving up hills and inclines

    not losing oil/coolant, the engine seems to be struggling, literary running out of breath

    You probably already did this but since you didn't mention it..

    Have you tried taking a look at your air filter, make sure it didn't get clogged up with something somehow? If it sounds like its having trouble getting air, couldn't hurt to check your whole intake system. Maybe some animal made a little home in your engine bay somehow. Have heard more than one of those stories around here. Just a guess

    no, its not that

    I spend close to 40 hours disassembling the whole intake, cleaning everything from maf to tb to intake manifold

    the car is down on power, the spark plugs look wet and oily, both threads and electrodes, no cel, doesnt loose oil etc

    strangest f...ing thing in the world....

    I was thinking maybe o rings, but this doesnt answer the loss of power

    I'm down to last 2 things, that I need to check, but not sure how to

    the throttle body, if its malfunctioning and not opening fully, then the air going by would not be enough for the amount of gas and air, would cause the sucking/puffing sound, + wet plugs

    the thing is there is no way to remove the intake and start the car to see if it opens fully, the engine just dies

    how did it start with you? anything unusual or just one day....


    I can't let it go, it makes me think there is something wrong with my car, plus wet plugs, long term it can not be good for our engines

    My observation.


    My mpg went down. Might have felt like a little less power too. Put in new air filter (22,000 miles). Seemed like power went up and did get a little smoother. Will need about a week to see if it improved mpg.

    Note: the filter looked pretty white but since it is about a year old I figured I'd spend the 14 bucks to be sure.

    thats my next job

    but the car is still pretty new

    it really feels as if the engine is not getting enough air and is being overflowed with gas

    I can smell gas from the exhaust in the morning......

    it should, that's exactly the reason why this is driving me crazy

    -sounds wierd
    -loss of power
    and no cels

    it can be something mechanical, bend valves, damaged o rings, damaged exahaust

    hmm one other idea, could you have damaged the mass airflow sensor somehow? I don't know if this would throw a code
