    Default Any direct injection owners here?

    I bought my first direct injected engine in a 35k mile Audi S5 4.2. Reading the Audi forums caused me to think that my cold start stumbling might be due to gunked up intake valves. Cuz I'm me, I bought a set of intake gaskets, a media blaster, and 25 lb of crushed walnut shells to deal with it. I drilled a hole in a shop vac attachment so I could suck up the shells as I blasted them. So far the project is going well.

    Yes. I've had several
    direct injection engines and working on the ecoboost.

    i was the one that diagnosed the problem for BMW 7 years ago.
    there is maintenance. Fabricate a tool that can high-pressure clean the back side of the valve, if there's not one available.

    A lot of people are adding port injection which I guess helps or eliminates that issue
