The code is for your throttle position sensor.
This sensor tells the computer how far the throttle is open, if this sensor is faulty the computer does not know how to manage fuel and ignition, or will not do it well.

Unplugging the map sensor only makes the computer revert to theoretical settings to allow the vehicle to run.

It looks as if your problem is with the throttle position sensor or its circuit.

Hope this brings you closer to a solution, remember to leave feedback and vote. Good Luck

Just turns off on it's own, Wait 60 sec. restart press pedel it dies.


This engine is electronically controlled so the first thing that must be done here is to have the systems control computer tested for fault codes and then do the proper diagnostics based on those codes.

Sounds like the Idle/Air Control Valve is bad. If you are able to remove it, you may find that it has some dirt or build-up in it and be able to clean it for it to work. This would more than likely be a temp. fix. Chances are you'll have to buy a new one.

Rough idle then stalls


Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

Wont idel when warmed up


seems to me there may be a problem with the transmission, because you say it runs fine in neutral and dies when you put it in gear!!!
only logical thing if everything else you mentioned has been ruled out!!!
