HI All,
Our 05 Mustang with the 4.0lt. and 55k miles has began to start a second or so slower than from new. We usually crank and it starts immediatly, now over the last couple of days it cranks for a second or so longer than normal before starting. New air filter, plugs and cleaned throttle body. Still no change. Any ideas would be appreciated.
Thanks
Bob

 

Check and see if the battery is still on top of its game, it can be reading 12 volts but still be going bad.

 

good call looks to be bad after a load. short life !
thanks

Get an Optima, it's worth it, I have 4 lol

 

+1 for the Optimas. They are pricey but they are really good. My car starts like its new.
