My car is doing strange stuff,,I have a cylinder misfire I put new coils and plugs and misfire is still there ,,but some days u start the car and it runs fine ,,other days it runs terrible ,, can any one give me some ideas ? One garage said ECM ?

 

Just did sea foam treatment through the throttle body, and my misfires for 1,4,5 are going away according to the scanner ,, it’s getting better as I start it up and let it get up to temp then I shut it off let it get cold then start it up again

 

I am new to the forum and shopping for 2018 A5 Sportbacks. I'm impressed with the car, both new and pre-owned. The question I have is does anyone know what "minor" changes Audi plans for the sophomore year of the car? I don't want to break my rule of never buying the first year version of a new model, but I really like it. Also, when does Audi normally release the 2019 models, early first quarter?
