cars running abit rough when idleing. its had a new coil pack, new water pump, new frnt suspension on drivers side, new plugs, a new HT lead, new cambelt and had the system flushed. i had a lot of problems tht have errupted in the past 3 days lol everything back to normal now its just running a little rougher than say a couple of weeks back. if i took it for a service would it cure the rough idleing? the engine sorta shakes a little. the exhaust also has a little "popping" sound. it just feels weird because it never used to do all this. used to purr like a cat =] now it sh*ts like a bull. so to speak =]
