10k ago had head gasket and timing belt replaced. Presently keep recieving a cam pos code and serious rough idle it happened over the course of the last few weeks. First i thought it was the spark plugs because of stalling at lights while in drive, once i replaced spark plugs no more stalling. the light came on again i replaced the sensor, it then came on two days later i replaced the sensor again. I do not know what other reasons could be causing the cam pos sensor to keep going off.

In need of any advice thanks to all that can help or try.
