First.. Did you ever check your gas cap to ensure it was a venting gas cap? and why start a new thread? Do you have any check engine codes? If fuel vapor recirculation system is not working correctly, it would flag a check engine light. Could also be a bad EGR... Your EGR opens when on the highway, if it is sticking open, when you slow down it would start to idle rough and eventually stall. (This is my primary guess). Spraying quick start only overloads the sensors and puts the system in a temporary closed loop set up bypassing all sensor reads. It should have a higher idle at this time (which is why it stays running).
