I replaced the NGK plugs with my preferred AC Delco plugs.......
Low and behold, I got easier starting, better cold idle and I also got a noticeable increase in low end torque.....the car will carry a higher gear through a corner than it used to. All together better to drive.
I certainly wouldn’t say the RAIV is a bad cam.
