Could an EGR valve be the reason that the car still misfire? Because I changed spark plugs and coils.

Yes, an EGR valve that does not close when it is supposed to can cause misfires. If you need more direction in finding the cause of a misfire, you need to add a real lot more details and information.

You will not get a dead cylinder misfire but you will see rough idle problems, normally a faulty EGR will give a check light. I would do a compression test and check for vacuum leak and ensure that the injectors are okay first.
