I am having a bit of a bog when I step on the gas. Every once and a while the engine will sputter while I am driving along. I already checked all the vacume lines and they all look good. The service engine light came on and the diagnostic report showed that it was caused by the Mass Air Flow sensor or the Manifold Absolute Pressure sensor. What do you guys think?

Well, which one? They're different, you know ............... Gimme the MIL codes AND the full text of the description and I can help you. The Cap'n
