Starting problems

[Guest]

2007 Jeep commander.when starting car in park it starts but run poorly sounds like starter is still engaged.Shut car off put it in neutral and it starts and runs just fine?

that is strange, the park and the neutral signal should both do the same thing when you go to start the engine. Is it always, noise when starting from park but normal when you start from neutral? Or is it an intermittent thing from park?

you should use a test light and see what the Yellow/gray wire from the starter relay to the starter is doing when you start the engine in both the park and neutral are showing. Is the starter getting a continuous power to the starter when you start it from park?

has there been any electrical add-ons to your vehicle? Stereo, lighting...
