SOURCE: my 2004 ford freestar van is hesitating going down

most likely not the fuel filter- try plugs and wires... could be a number of things, if the vehicle runs fine while in park and doesnt hesitate, most likely is sprk plugs and wires or a transmission problem...

SOURCE: engine hesitating during acceleration

Ok, there are many issues here that you will need to inspect. I recommend changing the fuel filter and pump as well. this will fix the hesitation. the intake and exhaust manifold gaskets will need to be replaced as well. this will stop the backfiring.

I also recommend checking and running a teat on the PCV valve and inspect the PCV hose as well. it could have a leak or a small crack on it.

Check the air filter and change if needed. this will help with acceleration issues as well. Next, i would run a check on all plugs and the complete wire set as well. change if needed.

Inspect the injectors for leaks and lose wires. make sure they are in good condition. replace any injectors that isn't firing properly.

Ok, there are some sensors that you will need to check as well. i will list them below.

SENSOR CHECK LIST--

1. Check the O2 sensors for worn wires.
2. Check the MAFS(Mas Air Flow Sensors) Check for Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit.
3. Check the Air Cleaner Temperature Sensor. this sensor could be damaged ro have loose wires. check accordingly.
4. Check the Throttle Position Sensor. this device could be connected wrong or it may be faulty as well. replace if needed.

Be sure and inspect all the above and repair any problem spot you ruin across during your inspection.

Please rate and god bless:)

SOURCE: 1995 F150 bucking and hesitating

look at the EGR valve.it should move freely..listen for hissing sound of an air leak,from the intake manifold...with that kind of mileage,it is likely .check the wiring on all the sensors,the map ,air flow,coolant temp,and the idle air speed controller on the throttle body.

I would take the truck to an autoparts store and have the fault codes retrieved from the computer. Most stores will do the scan for free. I would lean toward a faulty throttle position sensor, but that's just speculation. The fault codes should narrow the problem down. Hope this helped and best wishes.

I HAVE A 1991 3000GT VR4 MIT WHAT IT IS DOING IS WHEN I TRY TO PRESS ON THE GAS IT HESITATE?


Fuel-injected cars often experience clogs in the oil filter. This is especially a problem for cars that are filled up with low-quality gas and cars that have recently run out of gas. Try adding a fuel injector cleaner and filling up with premium gas for a couple weeks. In addition, check to see if the fuel injectors are functioning properly, and make sure the fuel pressure is within normal range.
For cars with carburetors, check the fuel pump. This is an essential part for fuel delivery, so it is the first thing to check when a car is hesitating during acceleration. It's also possible that the car is hesitating when accelerating because the carburetor is failing.
If the problem persists, have the spark plugs tested to see if there is a malfunction. Also inspect the wiring for frayed edges. Other things to check include the air filter, fuel filter, timing and gas leaks.

THE ENGINE LIGHT CAME ON THIS MORNING AND STAYED ON...IN ADDITION, MY CAR IS HESITATING AND MISSING..THE MANUAL SAID TO FILL IT WITH NEW GAS WHICH I'VE DONE BUT IT DID NOT HELP. IF I ACCELERATE FAST, THE...


The knock sensor is making your engine light blink, and motors "knock" when the gas in them does not have enough octane (poor quality fuel may have water in it) I would first try a bottle of octane booster in the tank. It simple makes gas burn better. If this does not help after 50-60 miles, replace your fuel filter, as you probably got some dirty gas which has partially plugged the filter not letting your car get enough fuel and could cause damage.

Hyundai coupe excessive fuel consumption


Unless the Check Engine Light is ON, there is no vehicle-related issue to fuel consumption. The computer will deliver the exact amount of fuel needed to satisfy the demands placed on the engine, using input from a large variety of sensors, including the accelerator pedal position sensor. Fuel economy estimates in the USA are just that, estimates, derived from a chemical analysis of emissions, and not actual driving. And no vehicle ever hits those numbers.

There are numerous outside factors that have a negative impact on fuel economy:
Vehicle maintenance, driving conditions (stop & go driving KILLS fuel economy), accelerator pedal usage, overall vehicle speeds, loads carried, etc.

Remember, the more you use the gas pedal, the more you use the gas station!

Strong fuel smell


You more than probably have a gas leak somewhere in the fuel system. If you can smell gasoline, it is leaking somewhere. The lines run along the frame to the engine. The leak might be hard to see or hidden (on top of the fuel tank).

The leak is robbing fuel pressure from the engine, causing it to idle rough, so is probably on the pressure side of the system.

(Most fuel systems, except for "returnless" systems with Pulse width modulated fuel pumps (not very common), have a pressure line and a return line to the tank.
