    Hi guys, wonder if this has happened to any 355 owners. My car has 24K and only drive it on weekends. Two weekends ago I noticed a (br br br br br br br) interrupted sound when accelerating. While doing that I noticed the gas intake was poor and last weekend it was doing it all the time.

    The br br br br sound gets faster when accelerating. It almost feel like gas filter isn´t clean, but it is new. "Check Engine 1-4" light comes up on and off. (Preasure regulators where changed at 15K).

    Thanks for your response!

    May be some misfire ....
    Can you confirm it is the "Check Engine 1-4" light which come on and not the "Slow down 1-4"? In any case, have a look to your plugs and plugs wires.

    You should pull the engine codes.

    You have a misfire that could be caused by a number of things.

    Bad spark plug wires
    poor/dirty connection for the mass air flow sensor
    bad rear cam sensor
    poor/dirty connection for the crank sensor, or even a bad crank sensor
    fouled spark plugs

    So pull the engine codes to get you pointed in the right direction. Be sure to pull the codes while the engine is idling.
