I am in the process of buying this salvage car with OBDII code readings P0305 and P0304 Misfire on cylinders 4 and 5. Wire, plugs, coils, injectors have already being replaced, and the problems persists off and on. What could be the problem and how expensive can it be?

HI there, thank you for the donation.

I would be checking for vacuum leaks and doing a comp test as well just to be sure, you have already done all the things that should be checked first, is there any indication of over heating or coolant loss? Until the problem mis known there is no way of estimating a repair cost.
