prolonged cranking to start and backfires when cold

I just replaced my opti and it ran like a friggin champ! I gained almost 2 tenths when i replaced my dying opti. Now (2 weeks later) the car ran a tenth slower and is having problems starting. When the engine is cold it takes a hella long time to start, and backfires when i rev it up. Now when its hot, it doesnt backfire, but it still takes longer than normal to crank it up.

Someone help please...
