the car in my sig is having a few probs.....i fixed the idle air control valve and got the rpms back to normal but in park or neutral u have to keep your foot on the gas to keep it running or it will stumble and then cut off.....the guy told me that it ran fine till the fuel pump went bad.....and after he changed it is when the problem arose .....im wondering if any ford guys or any of yall on here have had this problem and what steps should i take to correct it

The smartest thing Ford ever did was circle the problem

 

check your fuel filter and/or fuel pressure regulator.....also look for vac. leaks and check your MAP/MAF sensor
