Check all of your vacuum lines for leaks, your intake tube, and around your intake manifold and plenum. You can try cleaning the maf, use some crc maf cleaner or a little shot of brake cleaner. Remove the air box lid(or air filter) and you will see, inside the intake tube, the maf's sampling tube. That is what you want to clean, do not use a rag or touch the wires in the sampling tube. To check your fuel pressure, look down the fuel rail for a schrader valve(similar to your valve stems on your wheels). That is where you connect a fuel pressure gauge.
