      The fuel issue is most likely related to a clogged fuel vent tube (routed alongside the fuel filler tube) - this tube can be unclogged using a length of hanger wire. If the hanger wire does not work then the fuel vent tube will need to be replaced.

      Try these sources for the replacement part; www.fillernecksupply.com, www.partsgeek.com - among others.

      Not really more HP - despite the claims. Regular maintenance according to the vehicle owners manual will optimize both fuel mileage and performance.

      It's a better breathe than conventional air filter. It added a few miles more, it depends on driving habits too.

    My car has 105,000 miles on it. While traveling cross country, it started hesitating.
    I used a fuel additive and premium gas and the problem seemed to go away, but now I can feel it hesitating again every now and then. Going to bring it to a dealer. My mechanic back home (1000 miles away) mentioned thinking about changing spark plugs and changing ...

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      Have an assistant to turn on the ignition switch, while you listen to the fuel pump running for 2 seconds from the uncap fuel tank filler. No noise, take the next step.
      Try giving the bottom of the fuel tank a few whacks with a flat piece of wood or a rubber mallet while another tries to start the engine. You have a 50/50 shot at getting the pump going again and the vehicle starting. if it starts as a result of the whack then it confirms the bad fuel pump. ( fuel pump runs extremely hot and it always requires a cooling from the fuel and at least 1/4 of the fuel tank, replace the fuel filter, it's probably filled with sludge from the bottom of the tank ).

      Note: Spray some aerosol starting fluid into the throttle (CAUTION: Starting Fluid is Extremely Flammable!). Then crank the engine. If the engine starts, you do NOT have an ignition problem

    Can a clogged fuel pump make car misfire in one or more cylinders
    I start van runs good for a bit then the rpms go up and down then the van dies

      Yes, however more than likely the problem is related to lack of fuel pressure; clogged fuel filter, faulty fuel pressure regulator - check these items first before suspecting the fuel pump. The fuel filter is easily and inexpensively replaced; the filter itself is no more than $3.00 to $10.00 - depending on the source.

      You didn't say how many miles on the engine? If your saying, engine idling, smoke comes from the oil fill cap hole, sounds like blow-by, worn piston rings, possibly. Also, check the crankcase ventilation system. Usually the crankcase should have a slight vacuum to pull fumes from crankcase.
