Lately i have noticed that when i start my truck the start is really weak every now and then. Not the normal roaring start. I know the starter is turning over and the battery is good. Its almost like not all the spark plugs are firing or something. Im honestly not to sure what it is. Do you guys have any ideas?

 

How do you know the battery is good... Motorcraft batteries never started my truck as good as any other battery that ive put on it... I will never but another motocraft battery

 

Needs a new battery.

 

Check the free first. Terminals Lose? Test your battery under load.

 

Also.. Been there and done that with the battery testing on my truck... I have a thread somewhere telling about my battery situation that i fought with forever.... Ford would test my battery and said the test came back good ... Still had problems with the battery and they wouldnt warrenty it.. Finally just bought a new battery out of pocket.. And havent had problems with it since

 

Cool ill try that then guys thanks.
