The idling on this car has had a slight knocking sound but it gs off when engine is warm and i have never got a check engine light. i noticed recently when driving the car had a slight jerk but still no check engine light. until traveling on day it came on and i scanned the codes and replaced all applicable parts — the electrical system is pointing to a bypass hose which was changed as well as a camshaft sensor which still didi not solve the issue. i check online it found many others had this problem. My camshaft was ticking when the car was under warranty around 40k miles but now the car is not.
