Im installing fast intake on 99 trans am and there is a hole on the back where I believe the map sensor goes. My car has headers so how do I know whether Im just not finding the sensor or I just need to block the hole.

you have to have the sensor!! it's back there! find it! you had to have taken it out of the other intake manifold

I think it's called the Manifold Absolute pressure but don't qoute me. And I agree with the above mentioned statement, you need it, and it's there. You should have had to pull it off. It's about one inch by one inch with a lil cylindrical stubb coming off with an orange rubber seal. Has a connector just like the one you pulled off the MAF sensor.

Its there, you probably left it in the old manifold. You have to have it installed or else you will have a massive vacuum leak among other problems...
