Could be running rich or the timing is off and you are backfiring through the intake. Take care of this because if true you can f-up the MAS if it gets bad enough.

plus 1 on the timing. this happened to my cousing on his 93 lx because he wanted nitrous he lowered the timing too much and the car would backfire out the intake. good luck

Agreed, time to get out the timing light.
