Backfire? thru the intake, or after fire out the exhaust. Different problems. True backfire (thru intake) could be sticky intake valve or one that needs adjust ment. After fire usually indicates over rich mixture I.E. on carbs it's choked and on f.i. it's out of calibration.

My 2000 does the: "Er, Er.....BANG.....potato-potato- rumble-potato-rumble-potato-potato"

(Is this the same thing yours does?)
Keeps the neighbors on their toes.

I tell myself it is normal and that it could be worse! LOL
