Two of the codes are po340, po102, ihaven't had them reset I was told that they should clear after so many start ups and/or miles driven. I also noticed that my pcv valve makes a clicking noise that I can hear from inside my blazer I just noticed this today
my pcv valve is relativley new. I did'nt have codes cleared because the problems still present.
