So basically lately my 318is been running fairly rough done a full gasket change on the plugs and rocker cover and everything torqued down to spec i was told.. But still hasnt solved my problem car just seems to be missing and running a rough idle. Would this be my coilpack .? just kind of want to no as money is slim lately and no in a position for buying parts for trial and error at the moment any help would be great lads thanks
