AlexM Posted March 4, 2011 Share Posted March 4, 2011 Don't have an AEM FIC do you? Sounds like the behaviour my faulty one caused. It could be spark plugs / coil packs etc too, I can't remember everything I tried before finding it was the AEM. Link to comment Share on other sites More sharing options...
Homer Posted March 4, 2011 Share Posted March 4, 2011 Almost certainly spark related Brett, As a quick and cheap diagnostics drop some NGK coppers in there and see if it goes away. They're about £14 a set. It's a good time to check your coil pack clips too. Link to comment Share on other sites More sharing options...
