Maintenance/Repairs

I recently had the engine replaced in my 96 BMW 318i. It had been sitting in my garage for a year. Since the engine has been replaced it has had a lot of trouble idling. At stop signs and when I am slowly backing out of a parking spot the engine will die. If I put the car in park it will usually idle better as opposed to just being in drive and having my foot on the brake. Sometimes as the engine is struggling the whole car will shake. It seems to be worse when the car is warmed up. My mechanic said it was the old gas in the tank. He suggested I fill it up with premium gas when the tank gets down to ? full and do that 4 or 5 times. I?ve done that but it is not any better. Any suggestions or ideas about what could be wrong?
