    Feels like a low RPM.
    I feel a.slow acceleration. Sounds like it wants to shut off on me. It does turn off sometimes when the engine is on idle or waiting a red light light go Green. Any tips or help is greatly appreciated.

    Would be useful to know what year car/engine you have.

    Beyond that I would say start with cleaning the MAF (with approved cleaner) and cleaning the throttle body. If you don't know how to do so please ask and we can help you out.

    I used CATACLEAN and do feel a better acceleration but it feels like there's a misfire in the engine.
    The spark plug wires and spark plugs have been changed.
