help!!!, lt1 issues..
after replacing the starter this morning i put on the cap for my exhause cut-out and took it to town to get an inspection,
well i made it to town when all the sudden the car started sputtering and jerking and and then popped and released a small puff of balck smoke.
I then pull into a parking lot and decide to pull the cap off the cut-out only to find a ton of metal shavings.
at this point i thought the engine was blown and i was seeing the remain of by bottom end.
so i say screw it and go to start it anyways to limp home in sorrow,
to my surprise it starts up fine and drives fine down the road for about a mile then starts sputtering again and eventually quits.
i leave the car there for awhile and come back later to fin it start up fine again and drive fine all the way home.
now im clueless, i added some berrymens b12 to the fuel today before my mis adveture,
is there anyway this could have caused my plugs to foul out?
could it be my opti bitchin out again?
idk ive about had it with this car and am out of ideas,

anyone know what the prob could be?
also it seems to run fine when its first started and after a few mins it starts the sputtering/jerking things again,
im about to replace the plugs and see if it helps any...
sorry for the life-story but im getting desperate,
any help or advise is greatly appreciated
