What engine please?

1.4 v8 MPI

This will probably be coolant leaking into one of your cylinders (with reference to your other thread). Causes a bad misfire until the coolant gets pushed out.

As I told you on the other thread, check your sensors, run a diagnose on your car. You might have a faulty temp sensor causing your car to run way too rich on fuel. Does it smell like petrol from the exhaust when you start your engine ?

For now no there is no petrol smell

I doubt that, he'd be leaking a lot of coolant through the exhaust pipe, it would be a noticeable loss in the expansion tank.
