well i never really had any problems with the car starting before. but its sat for a while this past year. but recently its got a mind of its own. if i get into the car and turn the key to ignition, it tries to start itself without me turning the key or putting the clutch down. the rpms jump and i can hear it moving. when i try to start it myself, its rough and if i dont give it a ton of gas it sputters and dies and trys to start back up on its own. if it dies before fully running, i get a puff of white smoke from the intake and exhaust... ive replaced the opti and fuel pump in the past few years with very few miles on either. battery is brand new. not sure where my problem is.

its a 1997 SS M6, cammed, boltons. madz28 tune OBD1 from a long time back.
