Isn't P0108 a MAP sensor code (high voltage)?

What other codes are you getting.

Your MAP sensor may have died or shorted. Maybe you baked a couple wires together on the back-end of the engine?

That DTC is set if the pcm reads more than 4.9v on the signal return circuit for the MAP sensor for more than 4 sec. You should have low voltage at idle during high vac around 1.0 - 1.5 volts and high voltage 4.0 - 4.9 at WOT (low vac). You need to check for short to voltage, poor connections at MAP sensor, Poor connections at PCM if all is well then replace MAP sensor and have a nice day.
