My M3 has been in storage for the last 3+ yrs and was to be started everymonth varing rpm until temp was hot. Prior to going into storage the injectors were taken out and cleaned and new plug put in. I just got back to it and started and drove the car--it ran terribly on 3 cylinders or less. After driving it a short distance the next day I noticed i smoke was coming from the aft end in back/under the motor. No oil on ground. Suggestion on what to look at first to get it to run like it should.
