Hi All, I'm a newbie here so please bear with me
3 days ago I got "Wildcat" extractors and a 2" system put on my ba astina 1.8 hatchback and today the car started running like ****. Whenever starting to accelerate from idle (i.e. at traffic lights, turning corners) the whole car goes into a shudder and then conks out. After restarting the engine, I have to keep the revs up around 3500 rpm to keep the car from stalling again until I can get up and running. Spark plugs and leads look ok. Can anyone offer some suggestions? Do you think I need a Tune-up after changing the exhaust?
