Got strange ECU codes? Bad idle?, Poor running?...

Check your battery!

My aunt's 02 mustang had been idling really rough, eating gas, & throwing misfire codes. Then it suddenly would not start last night. Turned out the battery was dead. And it should be since it was never touched since she bought the car in 02. Almost 6 years to the day!
Popped in a new battery & everything went away. Cleared the codes, & runs fine now.

Tip for the day.

That is weird, I've seen plenty of weird things working at a shop for as long as I did, but never throwing codes from low voltage! Good tip

Not uncommon occurrence in the 3G TL, either.
