Welcome to the Forum!

It sounds like your PCV system is clogged. Unfortunately the fix is replacement which is a bit pricey.

When you say Engine Management System light flashing do you mean the Check Engine light? Have you connected an OBD-II scanner to read the trouble codes? What country are you located in so maybe we can help you better?
