    2.0 Turbo Engine Issues

    I have a Vauxhall Astra 2.0 Turbo Petrol 2005 Design.

    When I accelerate a little harder than normal between 2500 & 300 rpm the car sometimes judders/struggles and then the engine emissions light comes on. If I go above 3000 rpm and then accelerate there is no problem.

    The car runs fine apart from doing this and I have found that it does not happen if the engine is cool.

    Does anyone have any ideas what the issue could be?

    I have same juddering and constantly have my emissions light at the minute! I got the light though about a week after changing the plugs and about 2 days after fitting a new cat back exhaust system so i'm thinking mine is related to that, the juddering has always been there though!
