I am Derek, ASE master technician i will be happy to assist you with your question.
The next best test to perform is checking for proper fuel pressure. Low pressure will cause a misfire concern and a lack of power.
You will need a fuel pressure gauge, this can be found at most automotive parts stores. The gauge connects to a test port on the fuel rail.
Fuel pressure should be between 50 and 70 psi.
Also i would recommend cleaning the mass air flow sensor.
