If your fuel pressure is too low, there is definitely something wrong with either the fuel filter or the fuel pump. If there is a leak around the intake manifold or at the hoses from the intake manifold, it may cause a too lean mixture, which will cause your car engine to sputter. The easiest way to find this is to use an EVAP smoke machine.
What to do if your car engine is sputtering?
The seals and gaskets prevent exhaust gases and oil from finding their way to the combustion chambers. When these fail, you will start experiencing a sputtering engine.
