The motor started to run rough. It was ideling from 1500 to 2000 rpm. I was told it is the pressure control valve. I changed the diaphram in the p. C. V. It was torn . It also caused my rear main motor seal to start to leak oil. Problem only got worse as now I have a fuel injector stuck shut. I drive city only . Car has 76000 miles on it .
