A rouph idle or running rouph could be a couple of things

1. you may need to clean you carberator or fuel injectors.
2. you may need to change your spark plugs
3. if you can drive and be fine and when you try to get into the gas and it tryies to bog and idle rouph than you may have an hair line fracture in the distributor cap..
but it sounds like a fuel problem... also if you have run it low on gas latley you may sucked up all the dirt at thebottom of your fuel tank clogging you fuel filter... so check that as well. the fuel filter is usually the cheapest to change... if this doesn't help the only thing i can think of othe than that is check your catalitic converter it my be trying to clog and if it does your truck will not run right or run at can check this by taking the exust loose from the manifold and running your engine... if this doesn't help e-mail me and i will help you through this problem....

I have a 92 Plymouth Laser with 12,000 miles. The fuel went bad while in storage. The tank was removed and cleaned and the fuel pump and filters were replaced. The car runs rich and surges and is worse...

Did you check fuel pressure after replacing the pump ?
If the regulator fails, it would either not maintain normal pressure, or leak fuel into the vac hose.
If the mass airflow meter fails, it won't run and the check engine light would be on.
Have you watched the O2 sensor and engine temp sensor on a scanner to see what they are reading ?

Your fuel level sensor is on the side of your fuel pump inside the gas tank. The pump will need to be removed and the sensor straightened out... Since excess fuel is pumped back into the tank from the fuel pressure regulator, (as well as emission return and vacuum) they probably messed something up there as well and gave you emission errors.

No this is not normal at all and you have a problem. FI engines should start immediately and run great without any hesitation. It can be a partially clogged fuel filter. Replace the fuel filter ASAP. It can also be a weak fuel pump or defective fuel pressure regulator especially on a 18 year old car. Fuel pump is located on top and inside the fuel tank. The tank must be removed to replace the fuel pump. After replacing the fuel filter and fuel pressure test will tell you if the pump is going bad.

I need to change my fuel filter in my 98 Dodge Intrepid. I know I need to drop the gas tank, but I'll be honest I've never did this before. I would like to have pictures to see what it looks like.

300M, Concorde, Intrepid, LHS, 1998-2004 - Fuel Filter Removal & Installation The fuel filter mounts to the frame rail in front of the fuel tank. The inlet and outlet ends of the filter are marked for installation purposes. Install the fuel filter making certain that it is properly orientated.

NOTE The fuel filter is part of the fuel pressure regulator mounted on the fuel pump module.
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Properly relieve the fuel system pressure.
  3. Lower the fuel tank.
  4. Remove or disconnect the following:
    Negative battery cable Purge and vent lines Fuel line from the pressure regulator Filter/regulator by pushing in the locking tab, turning the regulator to unlock it and pulling the it straight up
To install:

  1. Push the fuel filter/regulator into the fuel pump module and turn to lock it into position.

  3. Start the engine, check for leaks and repair if necessary.

Fuel Pump - Removal & Installation
The in-tank fuel pump module contains the fuel pump and pressure regulator which adjusts fuel system pressure. Fuel pump voltage is supplied through the fuel pump relay.

The fuel pump is serviced as part of the fuel pump module. The fuel pump module is installed in the top of the fuel tank and contains the electric fuel pump, fuel pump reservoir, inlet strainer fuel gauge sending unit, fuel supply and return line connections and the pressure regulator. The inlet strainer, fuel pressure regulator and level sensor are the only serviceable items. If the fuel pump requires service, replace the fuel pump module.
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Properly relieve the fuel system pressure.
  3. Remove or disconnect the following:
    Negative battery cable Fuel tank
  4. Clean the top of the tank to remove any loose dirt.
    Fuel lines from the fuel pump module by squeezing the quick-connect fitting with thumb and forefinger

    Fuel pump module electrical connector from the top of the fuel pump module
  5. Using special tool 6856, remove the fuel pump locknut by turning it counterclockwise.
    CAUTION The fuel reservoir of the fuel pump module does not empty out when the tank is drained. The fuel in the reservoir may spill out when the module is removed.
  6. Remove the fuel pump and O-ring from the tank and discard the O-ring.
To install:
  1. Thoroughly clean all parts. Wipe the seal area of the tank clean. Place a new O-ring on the ledge between the tank threads and the pump module opening.
  2. Position the fuel pump module in the tank. Be sure the alignment tab on the underside of the pump module flange sits in the corresponding notch in the fuel tank.
  3. While holding the fuel pump module in place install the locking ring and torque to 40 inch lbs. (5 Nm) using special tool 6856 or a spanner-type tool.
  4. Install or connect the following:
    Fuel tank Fuel pump module electrical connector Negative battery cable
  5. Fill the fuel tank with fuel. Install the fuel filler cap. Turn the ignition switch to the ON position to pressurize the system. Check the fuel system for leaks.
Hope this helped.

Hey i have a cadillac sedan deville 1992 where is the fuel pump located

The fuel pump is located in the fuel tank. On these GM cars, the fuel tank must be dropped in order to change the pump. It is alos recomended that the fuel filter be changed at the same time which is on the frame of the vehicle, left side. the pump at autozone runs about $75 and don't forget the strainer for about $10. The filter runs about$10 also.
