First but of drama was this.
Red flag due to car on fire...(Spiro's brothers but that's for another story).
So turn my car off as per instructors instructions.....start it back up and I have 10 lbs of vacuum.
Shut it down for the session and make an emergency Saturday call to Brian which is triple his normal phone call emergencies from me.
He said check the map sensor lines and sure enough this one melted on the intake.
