Martinturner Posted February 2, 2012 Share Posted February 2, 2012 My gt started to miss and play up so got the code 23 maff sensor so replaced it . Still got problem so replaced the landa sensor coil packs and spark plugs still got the problem. When it's first started it's fine for the first 10 mins got boost and runs good but when heats up starts to run like it has no turbos and feels like it's missing and judders when I put my foot down. But if I take it real easy boats turbos work and drives ok. Why is it only when I put my foot down any ideas?... Link to comment Share on other sites More sharing options...
