I also smell something burning. Not sure what it is.
Why will my 2003 Intreped NOT go over 30 MPH? on 2003 Dodge Intrepid
is it shifting
Brake(s) stuck on? After driving a few minutes , stop and check all rims see if any are hotter than others....... Maybe fried converter (clogged/melted) , from running to rich? Need more details of conditions.
