I have a C180 when started from cold first thing it stalls,restarts ok but idles rough when you try to rev it above 2000 rpm it just splutters and misfires,when you give it throttle easy sometimes it will rev up but slowly.When vehicle is warm the vehicle runs alot better but still lacks in power.There is no fault codes stored someone please help any ideas.I have renewed spark plugs and leads does the fuel pump give any pressure problems that is what it feels like
