I also seem to have the same problem i have fmic, safc2 plus all the other mods. pulled the plugs out and noticed that the tip on one of them was broken, these ware iridium plugs. dont know if thats the problem but you could check.
I'm looking for some mesh that will protect my FMIC. I've got a GTR front bar and need the gap covered with mesh. Any ideas where i can get some black mesh similar to the stuff used on a GTR top grill?
