Ford C Max Vibration at Idle

DIYMart · 12-10-2014 3:42pm #1

Hi All,
I have a 2007 C Max 1.6 petrol that vibrates at idle. Vibration comes through the seats and the idling goes down/slow downs when the vibration happens. Ford dealer connot find anything wrong. They've changed plugs, coil, cheched mounts, suspension, cleaned throttle body, timing. Timing belt and Water pump also done. The ar seems to running fine but am worried it could be something big like crankshaft problem. Car is still under warranty so don't know what to do.

some feedback would be great . Thanks.

Crankshaft problems would probably show up as a horrible grumbling noise when starting the car.

I don't know if that car has a dual-mass flywheel, but if so, that could be the problem.

It could be something much simpler like spark plug leads, but I would expect main dealer to have found this through diagnostics.

Thanks for the reply.

I suppose I was thinking worst case scenario with the crankshaft. Car is starting ang running fine.

Searched on the net about the Dual Mass Fly Wheel. Seems they are only used in diesels to dampen the extra vibration so that's a relief.

Was talking to the mechanic where I bought the car. He changed the plugs and coil and cleaned throttle body.

He also took it to two ford garages and they both ran diagnostic checks. All fine. Timing OK also. He also sat in two petrol c maxs at the ford garages and both had similar vibrations. Maybe its just normal vibrations.
He seemed like a straight fella so feel a bit better now.

Here's hoping!

I suppose I was thinking worst case scenario with the crankshaft. Car is starting and running fine. Good power aswell.
