Hello, I have a 1998 CRV that struggles to start about an hour after last drive. In the morning when its cold it starts up first crank. We have a check engine light for a "faulty" cam sensor and evac sensor(?) but the car runs fine once its running, any ideas on why its struggling?

 

Cam sensor is definitely a possible cause of hard start.

 

Thanks for the input, bought a new one but when I went to install it i couldn't find any online source telling me how to replace it or even where it is located, any help?
