so im driving down the highway today and the car breaks down.before it took a crap i noticed the tach went dead.i was doing like 50mph, so the car shut off while i was driving so i threw it in gear to try to restart. and noticed that it would just go into a vacuum on my gauge and did start while rolling in gear. its looks like e tack bounces when i try to start it

the tach should bounce when you crank the motor over. My guess is something came loose, check the obvious like properly connected vacuum lines, electrical contacts, piping, etc

Hard to diagnose with so little information
