Help with my car

I have 2003 pt crusier 2.4 turbo problem 1.enegine light comes on 2.eneigne light analyzer say the problem is number 4 cylinder miss fire I replaced wires spark plug and coil the problem still comes up car mil is 1002000

I wonder what a compression test would say?

nope

Fuel injector malfunction?

How did the plug look, compared to the others?

I second the suggestion of a compression test.

It could also be a vacuum leak or head gasket leak or clogged EGR passages in the intake manifold causing uneven distribution of the exhaust gas.
