    Default Engine miss/sputtering

    So it just started doing this when I'm cruising at 50mph and I go to accelerate. Once I give it more gas it goes away it's just when I'm giving light easy throttle. From 0-50isj and past 60 it doesn't misfire at all and performs fine. Any input? Added ISO heet hoping maybe it's maybe water in my lines from the cold weather.

    Im a big believer in starting with checking ur fuel pressure. Key on... fire up... idle... and driving... once all that is confirmed ok... then look into ignituon... ie icm... opti... etc.

    Might be a dumb question but how do you check fuel pressure?

    Get one with the shrader valve end and it will connect at the end of the fuel rail. Someone may have a photo they can post up.
