    Bad sputtering when hot

    Guest-only advertisement. Register or Log In now!
    I have problem with my s4. When car is cold everthing is fine, when it warm up i have bad sputtering, speccially on high rpm. Under full load car is doing fine from 2000-3500rmp then sputtering till 5500 rpm. After 5500 it hit 7000 fast. Spark plugs are new. Can coilpack cause this, or maybe EGT senzor. On vcds there is no missfires only EGT error.

    I will post video later.

    Yes coilpack. Find out what cyl it is and swap coils and see if it follows. Very common for us especially if your stage 3. Bad coil
