running out of idea's what it could possible be , dunno if this helps but it's running FMIC, turbo back exhaust, KKR430, super spark coils (car has done this be4 these mods were done) and sometimes like ill be cruising in say 3rd you can here it sort of miss type of sound and can feel/hear it, on idle some times it will miss and back fire sometimes between gear changes
