2006 Chevy Malibu LS giving codes P0106 and P0420
My girlfriend's 2006 Chevy Malibu LS 4-cyclinder started giving off the following error codes last week:

Quick searches point to a bad MAP sensor for the P0106, and possibly a bad catalytic converter for the P0420.
According to my girlfriend, the car's performance has not degraded as far as she can tell.
Before I send her off to our friend's mechanic, does this combination of codes stick out as something obvious to anyone? Will a bad MAP sensor cause a false positive on the cat?
Would it be worth trying to clean it out first and see if that solves it? For example, I found one video that doesn't have nary a comment of the idea being garbage.. Basically says to get the gas tank to a half gallon, add 1 gallon lacquer thinner, and drive it for a while. Or is this simply a bad idea?

Lacquer thinner is not the same as paint thinner, which is naphthalene. If you are going to use it, I'd wear a respirator and gloves, cause that stuff is toxic as hell.

I just replaced a faulty MAP sensor on my 2004 Malibu Maxx. The symptoms were a bad idle, stalling, and the engine going into limp mode. You would definitely notice that. A bad 02 sensor will affect mileage and what not, so that might not be as noticeable if that is faulty.
