Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
Replace the excelerator pump in the carb,and make sure of the proper engine timming!
propshaft coupling is damaged
There are several things that can cause your 2002 Ford Taurus to hesitate when accelerating. A dirty air filter will cause the problem.
You might have a blown headgasket on top
Try a basic tune up. New spark plugs, wires, cap and rotor. When the vehicle is in first gear and you are accelerating, that is when the most load is on the engine. It sounds as though under a load, you are losing your spark because it is arcing out where it should not be.
A car that hesitates or stumbles when accelerating can have dozens of different problems. Have a knowledgeable person look at it or post a question detailing all symptoms, trouble codes etc.
hi it sounds like your universail joints or tail shaft
If the automatic transmission car jerks when accelerating and the dash does not indicate a gear, there is a problem with the transmission. Check the shift solenoid.
because it's only a 1.3 and because it's a turbo. look up turbo lag.
The shaking of the front end could be many things, personally I would check the wheel balance first. The gear stick wobble points to the gear box mountings been worn.
You can tell when your car will take too long to shift to a higher gear when accelerating. Your transmission can also jump out of gear as well.
Incorrect gear ratio in first gear.Incorrect gear ratio in first gear.
plugged fuel filter, the injector unit (vortec v-6, 4.3L) could be bad, dead plug(s)...
Check differential fluid and replace is necessary. This will help the gears from jerking. Also, check your vaccum hoses and make sure none are leaking.
low trans fluid level.
For practical reasons it is advantageous to have neutral near first gear since you typically use first gear at the lowest speeds and neutral only when the bike is stopped. They put it above first gear instead of below it so that some one can always find first if they keep hitting the shift lever down. That way if you ever need to move the bike quickly you don't have to be shifting up and down looking for first the way it is sometimes necesary to do for neutral. If a truck is about to run into the back of your bike it is very important to be able to be in first gear and accelerating right now, whereas it is almost never important to find neutral so quickly.
The transmission is not shifting in and out of gear or your front joint is going bad
There are a few things that can cause this problem. Something to check would be the fuel filter, fuel pump or fuel injectors, when cars do this it is usually because it is not getting the fuel it needs.
burning lots of fuel to get it going, its an old car.
You have a bad coil. if an automatic, it might not know wether to engage in 1st gear or 2nd gear
Hesitation when accelerating with tha a/c on is a common occurence with four cylinder vehicles. The a/c uses alot of the engines power and causes the hesitation. It is not usually a cause for concern.
main shaft bearing
trans is breaking. get a new one
