I have a 2001 Boxster 5 speed. I disconnected the battery for about 2 hours, when I reconnected the terminal and started the car it was like it's missing fuel. Back fire in the intake, feels like it's not running on all cylinders. Is it because the ecm need's to relearn and It's going to fix itself or what ?

The DME will relearn idle in less than 5 minutes.

Take it for a test drive - it should be smooth by the time you return - if not then there is some other problem.

if the car isn't running fine after a quick drive, it could be the MAF.

unplug the MAF's electrical wiring harness from the MAF, disconnect the neg battery cable for a few minutes, replace neg battery cable and give it a start. if it runs well, your MAF is probably bad. i had the exact same symptoms and when i disconnected the MAF it ran perfectly.

could also be the Air-Oil Separator feeding oil into your engine. has the AOS been replaced?

could also be other things...

let us know what happens.
