REV UP DRIVING OR SETTING AT STOPLIGHT

When it rains my 2000 ford ranger will lurch as I drive it. I sometimes have to keep my foot on the brake in traffic because it takes off too fast.
.
Right after it rains my ranger will rev up while I am driving or setting at a stoplight. When I take my foot off the brake it sometimes really revs up?

I would check the mass air flow or map sensor as atmospheric pressure effects both sensors.
