Why does my car stutter on the freeway?

Why does my car sputter when I Turn on the engine?
The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
What does it mean when your car engine is spluttering?
A spluttering engine is a cause of concern for many motorists. It could mean that your fuel injectors are clogged and are no longer supplying the right amount of fuel. If the catalytic converter is faulty, harmful gases can find their way to the atmosphere. Some of these gases, like sulfur, are identified by their strong egg smell.
What should I do if my car sputters when starting?
Fuel that is. The next time the vehicle sits, instead of immediately starting the engine, turn the ignition switch to the run position so the dash lights come on for two seconds and then turn the ignition switch off. Repeat this a half dozen times and then try starting the engine.
What causes a car engine to sputter with low fuel pressure?
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.
