Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
This sounds more like a head gasket issue. These engines today use a Metal Headgasket so they act differently that the old style paper gasket. When you had a Paper gasket blow, the engine doesn't run right and it will never clear up. With metal head gaskets, the way the actually show they have a problem is after the car has been driven and then let it sit. When you let it sit, the coolant system as it cools seeps into one or more cylinders. When this happens when you go to first start the car it will run ruff for a few and it will smell like it's running rich cause coolant doesn't burn and the gas hits the coolant and mixes with it to finally burn it. The way to verify is to add a dye to the coolant system when the engine is cold. Then drive the car and when you are going to let it sit, pull all the spark plugs. So the next morning you can inspect the cylinders for traces of dye to verify my thoughts.

What are the exact code numbers?
I would need the codes to really determine. It could be when it misfires it throws crank sensor code or when it misfires it throws the intake timing code.. It's hard to really determine with out the exact code numbers
