Astra From HELL - Part 5 (VVT P0016, P0014)

Now that the Astra is running, it is obvious that there are still some problems remaining with the engine. Intermittently it will throw VVT codes P0016, P0014 and run like poo. Also one of the oxygen sensors is acting up, and it s overdue for an oil change. What is the root cause? I find some interesting clues along the way, and discuss where to go next with the customer. Enjoy! Ivan
