Check the coil pack is generating spark for each plug. I had the same issue and did the screwdriver test, PS: be sure to wear insulated gloves, they have quite a kick. Remove the coil pack and sit it on its side on the top of the motor. Position a long screwdriver about 3 mm away from the end of the contacts and get someone to crank the motor for you. If you don't see a spark coming from one of the points that make contact with the spark plugs, you will need to get a new coil pack. Cheap on eBay.

Remove and clean the throttle body.
There is a small hole for the exhaust gases that gets blocked and leads to rough start up and idling.
I had the same problems as you, and after cleaning, the car is back to normal running.

Hey, I had the same issue. Just changed the coil pack and it seems 85% better. Also, check there is a small hose near your air filter, as if it's not on properly, it will run terribly.

I had the same problem... paid a mechanic to fix it, but I could barely drive it home. So I fixed it myself... changed the spark plugs. Behind the O2 for the air filter (have a good look) there is a black little air line that needs to be reconnected. It will stop the surging and you will be able to start and drive your car again.
