The Porsche dealer wants to do an air leak test due to CEL I get occasionally at or near redline. The Fault is misfire cylinder 1 and 4. I changed the oil the other day and found I have a leak somewhere in the filler hose. Knowing that the there is a vacum on the oil cap when the car is running that has something to do with the AOS, could this be the leak they are looking for?
