Problem began maybe coincidentally when my brother borrowed my battery for a day and when he returned it my car idles erratically and even died out a few times but since then it could not hold idle smoothly. Thinking that it was spark plugs I replaced them and during initial drive thought I had fixed the problem when rough idle came back the symptoms I felt was inadequate fuel causing hesitation so I gave it a bottle of fuel injector cleaner. Again in the beginning it felt as if this might have solved the problem but again like before as I drove the car the rough idle came back and I felt the car starting to lose power on inclines and from the line. I noticed fuel leaking from the fuel intake manifold cover (I believe it is) and continued to drive it when all of a sudden the car would not start up. It would crank but not allow itself to turnover...I sprayed some starting fluid into the air intake but it attempted to turnover but as I press the gas no pressure was present and the engine just died. My car is now stuck and I don't really know what to do next?! Can somebody out there please help??!!

Look for a test port on the fuel pressure regulator. It will look similar to the valve stem on your wheel where you add air to the tire. Connect a test gauge there..
IAC valve @ throttle body regulates the air/fuel idle. its right in front of the throttlebody, replace it, MAP sensor works together with IAC, both could be your problem. everything else you did is good, I feel these items are necessary to put you back in bussiness, just do it !!!
IAC Idle Air Control sensor is usually to blame. The MAF and TPS can effect idle also but usually IAC especially if it's erratic going up and down. If smooth idle but dies then maybe fuel pressure/pump problem or something is heating up and causing it to die. Especially a shorting sensor.
check the airflow meter it may be stuck and make sure the electrical connection to it is not loose and also check the hose leading to it are not loose or cracked they tend to crack at the bottom where you cannot see it unless you remove it and check
Try to disconnect the Air Flow Meter. It is the first plug just before the air filter/air intake box. If this improves your situation you will need to source a new or aftermarket Air Flow Meter.
