i have a 1998 a4 with 127k miles. the number 29 fuse keeps blowing. its an engine timing fuse. car runs rough when accellerating after 2k rpms. when the fuse blows it backfires. i just had a problem with the icm where the #2 cyl woulnt fire and am wondering if it could be a related problem? recently replaced the icm and 2nd cyl fires now. anyone have any idea what could be causing the fuse to blow? a wiring diagram would be nice. please help

 

I have this exact same problem, any ideas?
