my buddies car was turning off yesterday when he turns it on the rpm drops all the way down to 0 we dont know whats wrong with it it a 2002 ss m6 we driving on the freeway and out of nowere it just stalled and turned of all the lights on the dash came on and now every time he turns it on or shifts from one gear to another the rpm drops it only happens when its in neutral or were at a dead stop wtf is going on with his car

 

Throwing any codes? Any code history?

That's the first step in diagnosing a problem.

 

I Kinda Got The Same Problem Yesterday....A Little Bit Different Though.....Mines Was On Parking In Front Of My House And When I Turned The AC On It Just Turned Off....Everything And When I Say Everything It's Everything....And I Tried Turning It Nothing Absolutley Nothing Happened....At First I Thought It Was The Battery But I Took The Battery To An AutoZone And It Worked Perferctly And Now It's In My Garage Just Waiting For Me 2 Fix It....But I Don't Know Wat It Is....Should I Run Some Codes On It Or Do Yall Got A Clue Of Wat It Is???
