been havin none stop problems, just ad the wheel bearing done then this happens.
car keeps misfiring when foot is to the floor at low rev range but when gonin that gear it seems ok, got the red warning/handbrake light on and battery light on then eml comes on every now n again.
just done the paperclip test and it came up with codes
31 Engine RPM signal (crankshaft sensor) No signal
48 Battery voltage Low voltage
only just had new battery aswell, accidentally left lights on and it went flat other night but charged it back up and it worked ok when i put it back on the car.
any suggestions why its misfiring and running like shit?

battery light + handbrake = alternator not charging battery
i know this for a fact my belt snapped and this came on and it sucked the battery power on the way home

wasnt even alternator belt there haha 
replaced that now battery light and handbrake light has gone off
but car now misfiring full stop, check plugs and leads fine, had spare dizzy changed that fine.
did paperclip test and it threw up these codes now
48 Battery voltage Low voltage
66 Carbon Monoxide (CO) potentiometer High voltage
73 Air Flow Sensor (AFS) Low voltage
94 Hall Effect Switch (HES) High voltage
i think the battery code will go when the ecu has been reset but what are the rest ? lol
turning ignition 13 times didnt work mate, how do you do it?
cheers
