P0108....Manifold Absolute Pressure/Barometric Pressure Circuit High Input

P0104....Mass or Volume Air Flow Circuit Intermittent

think this is telling you you need a new mass air flow sensor

Although it sounds more like the problem has to do with your coolant temperature sensor, your P0108 means there is a problem with the MAP sensor.

P0108....Manifold Absolute Pressure/Barometric Pressure Circuit High Input

It's entirely possible the intake manifold gasket has failed. An engine vacuum leak is a potential cause of the P0108 code.

P0104 code is MAF or VAF. This can cause surging and rough running. If you disconnect the maf and find that it runs a little better, you can be sure that a maf replacement is in order. Double check the code by erasing it then roadtest. If code comes back then it is a hard code.
