When is the last time you changed your plugs? If no idea, change plugs and clean your throttle body. If vehicle still acting up after doing that, it may be your MAP sensor or ECT sensor.

don't think it's the spark plugs because when you do start it runs fine.going to try the MAP sensor . but will the MAP sensor cause the computer read camshaft position sensor Bank 1

Don't think so. When you changed your cam sensor I would have thought it would have cured that code.The MAP sensor's signals helps the engine control module determine what changes need to be made in the fuel mixture. These changes include how much fuel is injected and when cylinders are ignited.
