Rough idle/ check engine light on

Asked by Emx321 Apr 24, 2020 at 12:59 PM about the 2007 Mercedes-Benz C-Class C 230 Sport

Question type: Maintenance & Repair

I got a 07 C230 sport rough idle, also check engine light on,
And when I accelerate it doesn't have that quick throttle
response like before it gradually picks up speed and when it
hits 80mph it has a real hard time going past that speed
even thoug i have the gas pedal floored,so I changed my
spark plugs cleaned the throttle body and replaced the air
mass sensor, someone told me it could be Evr valve so I'm
not sure what else it could be.?

first thing you would do is read the code and go from there , I don't think you should drive it if there's a problem .
