Perform a compression test of all 4 cylinders and let us know the readings.

Here is a guide

Oops, yep there is a problem with the engine it either has some burnt valves, broken valve spring or a piston has let go. Please remove the valve cover to inspect.

Please let us know what happens, we are interested to see what it is.

Cheers, Ken
