Was a 197
just changed plugs a couple of weeks ago and i'm get a couple of niggles. when i stat to move with not a lot of revs its a bit jerky/juddery/hesitant and also it'll on the odd occasion if i'm going 30 and press down on the gas, it'll lose power for a split second, then kick back in, any ideas as i read somewhere or was told something that the 1.2 16v engine doesn't like NGK plugs for some reason, cheers for any help
