The carbon monoxide detector has a reading of 9-12ppm inside the car while the car is in idle or moving. It went down to zero after shutting down the vehicle for about a hour or so.
I didn’t see any exhaust leaks. The only problem with the car is water leaking into the trunk.
Please help!

Suggest you look for any black soot build up on all piping and connections from the exhaust manifolds to the tail pipe
Thank you for replying. To look for black sooth, I have to disconnect all pipes and possibly clean the pipes. Is it right? I wasn’t sure if there is a way to flush out.
Ummmm no.
You need to carefully inspect the externals of the exhaust system, piping clamp joints etc, for signs of soot ( meaning an exhaust leak ) that would may find its way in to the passenger compartmentSee if any of these are useful to you:

The carbon monoxide detector has a reading of 9-12ppm sometimes inside the car before I started my car (very first time starting the car for the day). Once I started driving, sometimes it came down to 0 with or without my windows down.
What could be the issue?
If your meter is reading with out the car running you have 2 possibilities:
First your meter is defective
Second is over saturation of carbon monoxide.
Might try leaving the windows open for a few hours a day and see if things change.When you said over saturation of carbon monoxide, do you mean carbon monoxide is more than what is naturally mixed? does it mean something is malfunctioning?
