- Dirty gunky grease on your cable is the cause. At lower speeds the cable binds slightly and then jumps when the binding is overcome. This causes the spedo needle to jump. I believe that the cable comes out from the spedo end. Pull out, clean off the old grease, use new graphite type spedo cable grease on the cable and reinsert. You may have to take the end loose at the transmission to reinsert the cable into the drive. Good luck,

What is the 'Compound Annual Growth Rate - CAGR' = 0.2493, or 24.93%. Thus, the compound annual growth rate of your three-year investment is equal to 24.93%, representing the smoothed annualized gain you earned over your investment time horizon.o calculate compound annual growth rate, divide the value of an investment at the end of the period in question by its value at the beginning of that period, raise the result to the power of one divided by the period length, and subtract one from the subsequent result.

- You're absolutely right! A faulty engine speed sensor can be caused by a bad transmission. In most cases, it's found on automatics. This is why it's very important to have your car regularly checked.f a car is experiencing any of the above symptoms, it is always best if you take your car into a local garage and ask them to run computer diagnostic tests on the vehicle to see if the speed sensor is functioning correctly.

Driving in second gear at 65+ mph It's definitely not great. The redline is there for a reason. The speed limiter can be either an ignition cutoff or a fuel cutoff - both will make the car feel very shaky. The most common bad consequence of an overspeed condition when the engine speed limiter fails to thwart the operator is a bent valve.

- If it's the speed and/or reference sensors, it could be a bad sensor or the clearance gap is too large (see Adjusting Sensor Clearance). 1  Disconnect the battery negative lead. 2  Disconnect the speed and/or reference sensor connectors at the back of the intake manifold. 3  Remove the sensor retaining bolt.

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.

Vasovagal Syncope Vasovagal Syncope. Vasovagal syncope is a common cause of fainting. The vagus nerve is overstimulated and causes the body's blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward to the brain against gravity. Without blood flow, the brain turns off.

- What we're interested in here is when you have to push on the pedal with both feet and the car slowly rolls to a stop rather than locking up the wheels, or when the pedal goes to the floor, won't pump up, and you have to yank the emergency brake or turn the engine off in gear in order to slow it down.f the emergency is released and you have a brake warning light with no apparent braking problems, it could be a sensor in an ABS system or an error condition reported by the power booster, but it could also be a failed switch on the emergency brake.

- When the travel speed is too high, the weld bead will be very peaked because of its extremely fast solidification. The forces of surface tension have drawn the molten metal along the edges of the weld bead and piled it up along the center. Melted portions of the base plate are affected in the same way.

Syncope (Fainting) What causes syncope? It may be caused by emotional stress, pain, pooling of blood in the legs due to sudden changes in body position, overheating, dehydration, heavy sweating or exhaustion. Syncope may occur during violent coughing spells (especially in men) because of rapid changes in blood pressure.

Phantom Traffic Jams: What Causes Mysterious Highway Backups? Sometimes highway traffic jams up for no apparent reason. There's no accident, and no real reason to step on the brakes — except to avoid hitting the car in front of you.OE PALCA, BYLINE: If you've done even a modicum of highway driving, you've probably experienced this: You're moving along at a pretty good clip when all of a sudden traffic slows to a crawl. You inch along for a while, and then just as suddenly, the traffic starts moving again.

- 3) (See the information in italics at the top of this page.) At the start of observations, a car is backing up across the start line at a constant velocity of 15 mph. The car continues to move backwards at that speed for 5 seconds. Then the driver applies the brakes and the car slows smoothly to rest in 5 seconds.

How are the colors of the aurora created? This is determined by the specific atmospheric gas and its electrical state, and the energy of the particle that hits the atmospheric gas. The atmosphere consists mainly of nitrogen and oxygen, which emit the characteristic colors of their respective line spectra. Atomic oxygen is responsible for the two main colors of green (wavelength of 557.7 nm) and red (630.0 nm). Nitrogen causes blue and deep red hues. This is the spectrum of colors emitted by the various atoms in earth’s outer atmosphere.

The Scoop on Poop It is caused by a temporary drop in the amount of blood that flows to the brain. Syncope can happen if you have a sudden drop in blood pressure, a drop in heart rate, or changes in the amount of blood in areas of your body.

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.

Why would a car only overheat when driving on highway not when driving around town? If the car has sit for any length of time a mouse or rat may have built a nest in the muffler or exhaust pipe. This causes back pressure to build up at highway speeds but not at short low speed in town driving. If one of the other ans did not fix the problem this is worth a shot.   another possibility is a blown or leaking head gasket.

Presyncope/Syncope The most common cause of both syncope and presyncope is a sudden fall in blood pressure. Sometimes there is an obvious precipitating factor (e.g. having a blood test or the sight of blood) but at other times it seems a random event.

Understanding Fainting -- the Basics A vasovagal attack happens because blood pressure drops, reducing circulation to the brain and causing loss of consciousness. Typically an attack occurs while standing and is frequently preceded by a sensation of warmth, nausea, lightheadedness and visual grayout..
