Could be wheel balance.
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.
yes
2005 Town and Country: my egr valve caused my check engine light to come on and the vehicle would miss at around 20mph to 30mph and occasionally stall while driving at neighborhood speeds as well. After replacing valve, no problems have been reported and the check engine light went off. the egr valve is located in the front of the engine with the mounting bolts behind the alternator.
Tires and/or wheels may be out of balance
check your tires for broken belts or if see if some of your lead weights are missing.if belts in tires or if they are out of ballance it will cause vibration at 30mph or higher
Car crashes at higher speeds are more dangerous because the impact forces increase as the speed increases. Higher speeds result in more kinetic energy, which translates to more severe damage to vehicles and occupants upon impact. In addition, it becomes harder for drivers to react quickly and control the vehicle at higher speeds, increasing the likelihood of a crash.
Friction slows down the motion of objects, so it does not cause them to move faster or fly higher. In fact, more friction can make it harder for objects to reach high speeds or heights.
Tire out of balance is the most common cause.
cranck sunser
worn brakes could be the cause or check the A frame bushings
cv axle The rear brake drums may be out of round also.
No, it will just reduce your fuel economy.
