Hello there, I have a Ford Mondeo 2008 2.0L Petrol whih has developed a problem over the last 4 days.

When I turn the engine on, the car shakes at what appear to be random intervals. This continues for as long as the car is running. If I go on my way, it feels like when you are running on the last few ml of fuel before the car grinds to a halt irrespective, particularly noticeable when trying to maintain a lower speed between 1-30 mph. Travelling and stopping makes no difference, the symptoms remain. I was hoping this problem would simply disappear.

I have a medium amount of engine oil and it isn't due an oil change yet, I do less than 10,000 miles a year.

I am quite concerned because even my passengers can feel it, meaning it is a particularly strong movement (smaller ones you would only notice as the driver).

A faulty idle air control valve would explain the problem in standing traffic but not the fact that you can feel something is wrong when on the move. The injectors were changed approx. 2 years ago so don't think this is the problem.

Can someone please tell me what they think this is and how easy it is to repair?

 

Is the car manual gearbox?.. If so it maybe your DMF (flywheel)

If it' is it may make a slight difference if u depress your foot on and off the clutch pedal?

 

Thank you for the reply, I hope it isn't the dual mass flywheel.

I just experimented with the clutch pedal as you described and it did not make a difference whether the clutch pedal was pressed or not.

Does this rule that out?

 

Change the coil pack.

 

Not sure what that means..

In case anyone has experience with the symptoms described, I have uploaded a couple of videos:


Any thoughts?
