I was driving tonight when my car began to tremble andthen the check engine /engine electronics light came on. Then i began to smell a rotten egg smell coming from the exhaust. Could water have gotten into the engine?

Hi there,

Thank you for the donation,

The smell is sulpher in the exhaust, this can be caused by a number of things, but before we start to speculate, we need to know what the set fault code is that the check engine light indicates, you will need to get a scan done to have the code read, this swill give us better insight inti this problem, start here.
