    B6 S4 warm start up issue

    Guest-only advertisement. Register or Log In now!
    On cold start ups the car starts up perfectly fine with the occasional chain rattle of course. Sometimes on warm start ups it will hesitate to start, when it does it will be at a very low rpm shake as if its misfiring and then seem fine. Yesterday it did the same thing except, I tried starting it and it stalled right away. Anyone experience this? Could it just be bad coil packs/spark plugs? Its also a 6spd btw. Thanks!

    Plugs might be fouled. Should be easy to check this.

    I have a b6 s4 and I had trouble starting, can not remember if cel was on but cleaned the throttle body and it started perfect.

    I am having the same problem. It's at the dealership now and they said there's nothing serious wrong with the car, just a little carbon build up in the throttle body.
