I have 2000 Mustang GT that won't stay running

Asked by harley_guy1 Aug 31, 2013 at 07:41 PM about the 2000 Ford Mustang GT Coupe RWD

Question type: Maintenance & Repair

After work today I got in my car and started it up ,it ran for a second then died,started it again then died again after it ran for a second,so I checked under hood nothing appeared to be disconnected,no cut wires and no cracked vac. lines and fuel pump kicks on at start,so then I started it up again then gave it gas after it started and stayed running as long as I gave it gas ,after reving the engine for about 10 seconds I let the gas go and it died,so I figured if it runs as long as I'm giving it gas I'll drive it home,so after driving on the highway for about 20 minutes I had to get off as my exit was coming up,at the end of the exit I had to stop,and the car ran fine running normal and idling perfect???.....Anyone have any Idea what wrong with my car? Thanks ...Jeff

I'd start by changing the car battery with a NEW one and clean the end of the cable that connects to the chassis with a wirebrush...microscopic corrosion will prevent full amperage from getting there~ "iffy" grounding is what is gettin' ya~

the fuel pump needs steady ground, the ignition system needs steady ground...your current situation is this, dis-similar metals with over 300 amps thru that connection where there are dis-similar metals...steel chassis and brass crimped lug will develop a "welding" that occurs leaving "brown power" which the ECU chokes on~

Sounds like possibly your idle air control valve needs cleaning or is faulty and needs to be replaced. Also clean throttle plate.
