i have a 2003 alero automatic here lately its start to smoke. burn oil leak oil. has slighty miss to it now. it has 150k miles on it. went 100 miles from home where i filled the oil up cause it was low and when i checked before i left where i went it was two courts low again. any suggests? i just changed the spark plugs last night before i left where i was and it doesn't smoke as bad and its still has a little bit of a miss.

 

I would say the piston rings are bad.

 

Glad I could help. Now everyone should go buy a gls alero for the wheels and do the swap. It is worth it
