Is it a ram 1500 or 2500? sounds like you have a bad MDS solenoid you have to pull the intake manifold they are under it. Also when is the last time you changed your oil? How often ect and what weight oil are you using all of that will effect MDS.

It is a 1500, last night i changed the oil and this morning seems to be happy. We will see, if this does not fix it will look into the MDS solenoid. Thank you for the response.
