    Prepare for the worst and hope for the best is all I can say my friend. Keep us posted on the diagnosis.

    Just remain calm, it will work out.

    Random misfire code. When did it come on hot or cold engine? What brand fuel do you run and octane?

    When I started the car in the garage it was shaking a little for 2 or 3 seconds then it was fine. I went to the corner store and on the way back the check engine light went on. The out side temp was in the 80 and the water temp was 214. I use 93 octane.

    Good recall tell dealer that when it goes in. P0300 means it knows it's misfiring but doesn't know where. Best bet is drive it more to see/feel vibration and note temps and how much throttle. It may finally figure out what cylinder is causing it. What brand 93 ?

    I always put 93 octane from Sams because that's the only gas station near me with 93 octaine. I put 91 octane at a corner gas station three days ago because I was almost out of gas.

    Do you have a 6 speed or A8?

    There is a flash out for 6 speeds that will address an erroneous code P0300

    I am back from the dealership and they couldn't look at my car because they are backed up for 3 weeks. I called other dealerships and the same song 3 weeks.
    Today the car ran fine with no problems. The dealer told me I could drive the car as long as the engine light is not flashing. The engine light is on but not flashing.
    I also asked if the could fix some paint problems and was told to take it to the dealer where I purchased the car. I bought the car 200 miles away from my house. Dodge are you kidding me!
