On a morning I get in the car and press the clutch and start the car using the button as normal but sometimes I can hear the car trying to turn over but nothing happens, then if I turn it off and try again it fires up as normal. Also Im not sure if it has anything to do with it but when I am in idle for a long period of time the car has a progressive violent rhythmical jerk. I have used injector cleaner a few times but it still happens. The car is a 1.4 16v petrol and idles at 750rpm (i dont know if thats normal) I have also just cleaned the throttle body and put the car through a service. It has around 65k on the clock.

  • Are you sure your car idles at 9500rpm? That's probably just a bit lower than a jet engine idles ... Maybe you meant 950rpm? – Pᴀᴜʟsᴛᴇʀ2 Oct 9 '15 at 11:46
  • God no! thats a typo its ~750 haha – Anthony Broadbent Oct 9 '15 at 12:43

I have fixed this issue. To fix it I did the following: New air filter New spark plugs New coil packs

But the thing that really helped is cleaned the throttle body with carb cleaner and a tooth brush.

While I had the engine open and the throttle body exposed I cleaned the air inlet manifold with carb cleaner too and checked the seals to make sure there were no leaks.

I also now need to change the engine mounts because they have prematurely worn due to the problem
