ok so i disconnected my maf and attempted to crank my car to see if it was working or not. Well naturally my car did not start with out the maf. so i reconnected maf and attempted to start. well when i did smoke poored out of the intake filter...what is the cause of this? i started again and it was fine never did it again... i do notice a loud pop every now and then that you can feel in the motor when you give it gas...
