I have a 2004 mercedes benz c230 kompressor sport, recently the check engine light came on and the car is sputtering, rough idle, poor acelleration
My car's engine light came on and the car is running sluggish, sputtering with poor
acceleration. I turn the engine off and turned back on and the car runs beautifully but
then it starts to sputtering again! I took it to Autzone and did a diagnostic on it, at first it
was saying that #1,2,3 spark plug was misfiring and the computer was not responding.
They told me to go home and unhook the battery for about 2minutes, I did and the car
was running like new but later on that day it was back doing the same thing as before,
the computer isn't responding and spark plugs 123 are misfiring. What could cause this
malfunction?????? I desperately need your help :-(
