hi guys, i am sure there are countless articles on this but i am still looking for some other views on this. For about the past month my mustang has been having rough starts, on the first attempt the car may not start at all, second attempt will sometimes start up and then die right away and will finally turn on around third attempt. When it turns on it is not a clean start up, the engine sounds like it is struggling to keep it running the first few seconds. Once in a while it will turn on first try. I have noticed giving gas right as the engine turns on helps keep it alive and running. I have heard everything from bad fuel injector to maf sensor to iac but i was just wondering if anyone else had insights on this. thank you.

Update. I cleaned throttle body, IAC and MAF sensor. Car does appear to be run smoother however still hesitates at start up, car starts up if i give it gas at the start. also disconnected battery for computer reset.
