my radio wont play cds. I tried running a CD cleaner but keep getting PEO code. Then it ejects CD, and I also have a code that is a seperate code. Check engine light that says egr needs to be replaced. while I replaced the EGR valve with one from standard elctronics because it was a lot cheaper than a honda one. But the check engine code still wont go out for very long. Does anyone have any advice on these 2 seperate issues?
