Scoobyghost Posted June 1, 2016 Share Posted June 1, 2016 Could be many causes. What fuel are you using? Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted June 1, 2016 Author Share Posted June 1, 2016 Normal 95 at the moment Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted June 2, 2016 Share Posted June 2, 2016 That would be the first thing to change. Using a higher octane fuel ideally 99 will reduce knock/detonation which means the sensor won't be telling the ecu to ret.ard(avoiding swear filter) the timing.

Phillip1993 Posted June 2, 2016 Author Share Posted June 2, 2016 Ok wot else could cuse the problem do you think Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted June 2, 2016 Share Posted June 2, 2016 Old spark plugs, weak engine mounts, dodgy sensor. Before running down the more expensive route, try a tank of high octane fuel through the car and you'll see an improvement all round. Even if the knock sensor is slightly lose it will rattle and "detect knock" quite a simple sensor really. Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted June 2, 2016 Author Share Posted June 2, 2016 Ok I will try that it has had a new sensor already and new plugs Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted June 5, 2016 Author Share Posted June 5, 2016 By the looks of it this is all down to bad coil packs Quote Link to comment Share on other sites More sharing options...
