ok spelling errors its buick not bucik lol and finally quick not quci k lol sorry about that guys oh and got the plugs in =D

It sounds like a tune-up is in order. Use quality parts, and change the plugs, wires, PCV valve and fuel filter. If that doesn't fix it, then you may need a catalytic converter. Do you have a "Check engine" light on, and if so, what codes are stored?

no there isnt any check engine lights on or service any thing like that... well then I was driving tonight and my low coolant light came on... so i stopped and checked it out and I had a full resivor so i continued to drive.... but then towards the end of my night the car started billowing steam and burnt antifreeze:banghead: so bad you couldnt see throught it....:uhoh: but i will go get it tuned up but any ideas on why it would just randomly start smoking? also with the dieing problem it still randomly does it but after a while of driving it settles out but then acts up again....
