Yesterday while driving for 2 minutes, check engine came on and engine started vibrating at traffic light (low rpm) like I have misfire in one of the cylinders, I turned back home, turned the car off, started engine again, check engine went off and engine was running just normally, I ran code with OBDII I got P2006 (Intake manifold Runner Control stuck closed), P0011 (“A” Camshaft Position Timing over…) and P0306 (Cylinder 6 Misfire), cleared the codes but codes came back again ( still engine runs normally), I almost know what each code means, but what could cause all these three errors come up simultaneously?
