Rough idle cold start only ?

[masterquestxp]

Hello my car has a rough idle the first 30 seconds after the cold start up. I start the car and the revs go to 1200 rpms and the engine shakes first 30 seconds when the engine slow down till it stabilizes at the normal 600-700 rpms then all is good ! Please help me resolve this issue. I changed spark plugs and air filters recently and problem still here. Then only code ista/d is giving is 002B63 dme camshaft exhaust sensor. Is there a connection ?

Bad cam sensors will cause rough idle. Change the sensor and it will resolve the problem.
