3. sometimes car barely wants to start--like seems like starter is starting but getting no gas...twice i've had to hit the gas to get the RPMs to stay up long enough for the car to not die

'05 GT mustangs are NOT coming out quick enough!

if someone could please help me out, that'd be great
if it helps, i just got a new battery the other day-- im thinking maybe the computer is shorted or something, fuel pump?? i dont know (obviously)

thanks in advance

I cleaned my IAC, quite some time ago, but I recently started having creeping-up idle problems again, with engine at normal operating temp...RPMs around 1,300 - 1,800

Changed my IAC at the same time that I cleaned my UIM/LIM...back to normal now.

Might want to clean your Throttle Body/Thottle Plate, if you haven't already done that. Your IAC is probably your main problem.
