So today after work I started my car up and it turned on automatically, adter i drove for about 2 minutes, it just shut off. I tried turning it on but didnt start. Once in a while it would turn on, stay idle for about 30 seconds but shook very terribly then it shut down. Also if I stepped on the throttle, it would turn off immediatly. Any ideas what it could be? Its my daily so I need help ASAP! Thanks, in advance!
