If fuel pressure is good, it tends to be a maf problem.

not to sound stupid but how do I test the fuel pressure?

Go to local auto parts store and get an actron fuel pressure tester, use the adapter thats in the kit for ford and hook it up to ur schrader valve on ur fuel line its on passenger side fuel rail near the front and in a haynes manual it will tell u waht it should be at with vacuum line on and off while running.
