My sister has been having occasional starting and loss of power issues. Codes at Auto Zone were #420 and 335; crankshaft position and Cat converter issue. Vehicle was going into flashing CEL after starting up and going up a hill within a couple minutes, you'd have to pull over and let it sit for a few minutes then it would run fine. I ran it for an hour and a half with no problems today. My sister drives like the proverbial old grandma.
