Are there particular circumstances when it hesitates? (engine hot or cold?, damp outside? certain speeds?, from a start?, etc. How many miles are on the car? Is the check engine light come on? When was the last fuel filter installed? When was the last time the throttle body was cleaned? or air induction service done? Open the hood, look at the back of the engine on the driver's side, is there oil seaping about 6 inches from the top of the engine? What did the spark plugs look like when you changed them? When were the wires last changed? Do you keep an eye on the oil level? Does it consume oil? What is the 8th digit of the vin? these answers will help.
Check for leaking hoses such as vacuum hose. Check the spark plug wires, are they connected properly, are they too old. take out all your spark plugs and check each one to see if they have enough gap at the end of it. not enough gap can cause a miss fire. do a fuel pressure check, with a fuel pressure gauge. if your car hesitates during start up, check you camshaft sensor. if you have a diesel car, check you glue plugs. its located beside spark plug
"What causes cars to hesitate?
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.
Sounds like it could be a dirty fuel filter, try taking it off and cleaning it.
The problem is likely an electrical one - check your spark plug leads from the distributor to the plugs.
Most likely you have an ignition misfire. Check ign coils, ign wires, spark plugs etc.
Some people hesitate because they want to pause and think things through, others are afraid or uncomfortable.
You provide limited information but at first glance it sounds like a problem with engine timing (perhaps spark plugs). I would take the car to a mechanic for diagnosis.
A 93 Town Car can hesitate when you first turn it on in the morning because the air filter is clogged. It can also be caused by bad gas.
A leak in the brake booster is one common reason why a car would stall or hesitate when the brakes are pushed. There could also be an obstruction in the brake line.
poor tune up.
it could be your air filter, you might not be pulling enough air into the engine. it usually costs less than 10 to fix
Because its an old french car!
Time for a tune up.
Your car might hesitate under acceleration when the weather is wet because your tires are worn or because there is water in the gas. You might also have a problem with the fuel injectors.
The car will idle rough and hesitate during acceleration.
Because it is too tired from all that driving
An air conditioner in a car uses quite a bit of power. It is not unusual for a car to hesitate when the AC comes on.

u should get a complete tune up asap.

Could be, time for a tune up.
I had the same problem with my eh Holden and found that the carby bowl was dirty and the main jet was blocked. if its on a injector car try cleaning the injectors with a fuel additave Ken
Many possible causes. For starters get caught up on your maintenance needs.
A bad o2 sensor can cause this problem in a car. A bad fuel pump, fuel filter or fuel line will also cause hesitation during acceleration.
check the fluid if that is ok you mite need to change the filter
