    Have you tried new plugs? Old gas won't do this unless it is full of water.

    Bad plugs cause all kinds of running issues with the DI motors

    What exactly is it doing before it starts?

    Unplug the TPS connector. Does it now start better and idle normally?

    It cranks over and then hits a hard spot and stops then try again and it will start and run for a couple sec some times and then other times it starts and dies right after words when it ran for a few seconds it seamed to idle fine till I gave it throttle and did not unplug tps plug will do tomorrow

    Right now this sounds like an EMM internal problem.

    One of the ways an EMM can fail is for the ignition timing to jump all over the place. The result is firing at the wrong point in the piston stroke and sometimes backfiring through the exhaust or intake.

    Unless it starts and idles nicely with the TPS unplugged, my guess is that the EMM needs repair. The most common repair for crazy ignition timing is replacement of capacitor C89 inside the EMM.
