Hi. Just joined. Apologies for any mistakes.
I was driving on a freeway when the check engine light came on and then wouldn't go faster than 60 mph then 50 mph at night and in the poring rain. I was able to get off and when I did park and turned it off, it shook. I checked all the fluids and everything was fine. I then started the car, the CE light was gone and I could drive normally. What the heck happened. I have a 2014 fortwo in CA. Thanks in advance.
