Started the car and it was like shaking or shuddering in just idle. I went for a drive, and it drove fine. When I arrived home, I parked in the garage and again in idle mode was missing. I replaced the spark plugs and noticed the car still shaking in idle on and off now. I noticed on getting out of the car I could smell petrol fumes.

It sounds like you have low compression or a bad fuel injector in one cylinder, we should run a scan, this will tell us which cylinder is having the problem.

So, this morning I started the car and at first it was shaking but once I got going it was driving fine. Still getting a strong smell of fuel once I park back in the garage.

I would not drive the car until the gas smell has been identified. Please use a flashlight and check the fuel injectors, this is a common place for fuel to leak. Check out the images (below). Please let us know how it goes.
