- An engine that hesitates, stumbles or misfires when accelerating or when it is under load, is an engine that is either sucking too much air, not getting enough fuel, or misfiring. If the Check Engine Light comes on, you may find any of the following codes: P0171, P0174 Lean fuel condition codes.

The Mineral fluorite In fact, the word fluorescent is derived from the mineral Fluorite. The name of the element fluorine is also derived from Fluorite, as Fluorite is by far the most common and well-known fluorine mineral. For additional information, see the gemstones section on Fluorite.he Mineral fluorite. Fluorite is a very popular mineral, and it naturally occurs in all colors of the spectrum. It is one of the most varied colored minerals in the mineral kingdom, and the colors may be very intense and almost electric.

What Can Cause a Car to Hesitate? Engine hesitation can be a result of low fuel pressure, vacuum leaks, worn or dirty spark plugs or bad spark plug wires. A weak ignition system can lead to misfiring, which can also cause hesitation. Continue Reading.

Improper Ignition Timing If it is ignited before top dead center it can cause the valve train to generate a noise that is known as engine ping. In most cases engine ping is caused by timing that is too far advanced. If the timing is too far retarded the most likely symptom would be a hesitation lack of power and very poor fuel economy.ow to test for improper ignition timing. When the ignition timing is not correct there are a few tests that can point to the car problem. The main symptom of a timing issue would be incomplete combustion at different engine speeds.

Compressor Stall â Turbine Aircraft Engine Compressor stalls cause air flowing in the compressor to slow down and stagnate, sometimes reversing direction. Typical Causes of Compressor Stalls Excessive fuel flow caused by abrupt engine acceleration when the axial velocity (speed) is reduced by increased pressure in the combustion chamber due to the added combustion and the resultant rotational speed increase

What causes the pinging noise in car when accelerating? Pinging is caused by pre-detonation, which can be cause by timing being advanced too far. But since modern cars' timing is controlled the computer, it's highly unlikely you have a timing issue. What's more probably is that the spark plugs are worn out and need to be replaced.

Engine Pinging Engine pinging also refered to as pinking, detonation or knocking Pinging can be anything from a loud knocking noise to a soft tinkling sound that is emitted from the engine. If an engine has a tendency to ping, it usually becomes first audible when operated in the lower rpm range and during acceleration. Pinging tends to fade away with increasing engine revolutions. What causes pinging?

- So your engine is idling poorly (shaking, misfiring), and you are not able to accelerate properly. There are a number of potential causes for this problem. These include: - Engine mechanical problem (low compression in one cylinder) - Plugged or defective fuel injector.

Rough Idling Both conditions can cause a P0171 lean code, rough or unstable idle and sometimes even a stalling condition. Rough idling can also be caused by bad motor mounts, an engine misfire, incorrect ignition or valve timing of even bad tune up parts.

- A Diesel-Like Clattering in Your Gas-Powered Car. Worst-Case Scenario: Detonation, also known as pinging or knock. Why: Things like bad gasoline or incorrect ignition timing cause the fuel to go boom too early. If left unchecked, you risk serious engine damage. What To Do: Switch to higher octane gas, which resists detonation, and check the timing.

- Gasoline engines run an aggressive spark advance curve and rely on EGR to prevent engine ping. If the EGR valve has clogged or stuck (or been blocked by those seeking to improve mileage), the quick advance curve will cause the engine to ping. If all else has failed, verify that the EGR circuit is functioning properly.

Abnormal engine noises are trying to tell you there is a problem Today's car engines are designed with more complexity and moving parts than ever before. When you hear abnormal noises there is something wrong. Some high output engines have short skirt pistons or roller valve trains so a minimal amount of ticking is normal when the engine is at idle. Fuel injectors also make a slight clicking noise when the engine is idling as well.

Why Does My Car Idle at a High Rpm? If the carbureted vehicle continues to idle too high after warming up, it may have a defective power circuit or accelerator pump. Replacing the accelerator pump or carburetor usually brings the idle speed to normal. Ignition problems sometimes lead to a fast idle.

Engine hesitates during acceleration Inspection Service A vehicle that struggles or hesitates to accelerate may be unpredictable and moments of hesitation may be coupled with equally dangerous moments of surging or unexpected acceleration. When a vehicle is hesitating during acceleration, it should be inspected by a mechanic. How this system works: A vehicle with a combustion (gas or diesel) engine requires an exact mixture of fuel and air to run efficiently.

Problem: Engine Hesitation Problem: Engine Hesitation. Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle. The problem often means the air/fuel mixture is not being properly enriched or is going lean, or the ignition system is weak and is misfiring when the engine comes under load or the air/fuel mixture goes lean.

Car jerks violently-bad transmission, sensor or fuel pump?? HELP! - Maintenance and Repair Forum If so have the fuel pressure checked.. It might be the fuel Pump. If the engine is running lean from from lack of fuel pressure the PCM will increase the pulse width to help over compensate for this cause the motor to load up on fuel which cause the care to hesitate.

What causes an engine to make a knocking sound? In C.I. engines auto ignition is key to combustion, but if the fuel takes some time to vaporize & prepare for combustion then some fuel is accumulated in chamber when auto-ignition starts at end of compression stroke, which causes a sudden large amount of energy release and abrupt pressure rise, and causes knocking sound.

- My car (99 dodge stratus, automatic, 2.4 L, 148K miles) has been developing a strange problem over the past few months that I have unsuccessfully diagnosed. When slowing down, even from 10 mph, the RPMs will drop as low as 250 and the car will begin to shake. Often, especially when making a sudden stop from high speeds, the car will actually stall. The check engine light is on and returns a running lean code.

Car safety information I was driving my 2005 suzuki forenza uphill going 35 mph when it suddenly stopped accelerating and sounded as though it had shifted into neutral. however, the car was still in drive. the check engine light also came on.t: caller has a 2005 suzuki forenza. car jerks without warning because the adaptive transmission learning software in the compute is defective. caller says the adaptive transmission shifting is affected by the computer problem, and the car hunts between gears, and that is why it jerks.

What Causes a Car to Run Rough? A bad hose in any part of the engine is easy to fix. Sometimes, vacuum lines cause a rough idle due to a vacuum leak, and these lines are also simple to replace. A common cause of an engine running rough is faulty ignition timing. Once the timing is adjusted, the car should run smoothly. The idle speed may also be set too low. Other problems in the ignition system that can cause rough idling include faulty spark plugs, rotors, ignition wires or distributor caps.

Carburetor Jets Air / Fuel Mixture. A lean fuel mixture (too little fuel for the amount of air in the cylinder) can cause an engine to stumble or give a rough idle as well as to run too hot, overheat, and cause a lack of power as well as engine failure.f the carburetor is supplying too lean of an air/fuel mixture, the engine will run sluggish, overheat or the lean mixture could cause engine damage. If the carburetor is supplying an air/fuel mixture that is too rich, the engine may tend to load up, foul the spark plugs, run sluggish and lack power.
