Change spark plugs, lead coil and compression check. All fine. Changed injectors, change crank angle sensor, change ECU. Still misfire on three and four.

May be a blown head gasket starting between 3 and 4 do a leak down test and also check for a leaking inlet manifold gasket at 3 and 4 spray a little brake clean around the manifold while running to see if the revs lift, if so you will have a leak.
