plug leads a common fault soak in wd40 start engine if one faulty it will pop out this is caused by spark escaping and igniting wd.
I have had a similar problem i have found the problem it was the clutch adjuster at the top of the clutch pedal, it had not been fitted properely and also caused my car to shudder. so please check above the clutch pedal and ensure the clutch adjuster is securely on.
