When does your car hesitate at 45 mph?
I started getting a hesitation/bucking in my 2001 F150 SCREW 5.4L 96,000 miles. It does it most often when you are barely on the gas at 45 to 50 MPH and then you press the gas to accelerate. It hesitates for a second and then takes off.
Why does my car hesitate when I step on the gas?
When you go to step on the gas pedal to accelerate, you will suddenly feel like the power has been lost in the engine for a couple of seconds. Instead of going faster by stepping on the accelerator pedal, the speed will be reduced. The vehicle may even stumble entirely during these seconds. This is what it means when the car engine hesitates.

Instead of going faster by stepping on the accelerator pedal, the speed will be reduced. The vehicle may even stumble entirely during these seconds. This is what it means when the car engine hesitates.
What causes engine hesitation on a Dodge truck?
The engine hesitation on your Dodge may be created by problems in one or more components. In most cases, a bad throttle position sensor (TPS) fails to signal the engine computer about throttle operation. Other causes may be bad or worn out components in the ignition secondary system, causing the engine to accelerate poorly and even stall.

What happens when you go to 45 mph?
I have a 97 f150 and it did the exact same thing after it was up to the mirrors in mud. What happened was I pulled mud threw my intake and went into the third cylinder and it started missing. Its most likely a misfire. It wasnt a hard fix I just cleaned the sand and mud out and gave it a tune up right then while it was all apart.
Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light

Why is my Honda transmission vibrating at 40 mph?
Bascially my father in law swears by it and if you get them done every 30k miles they garuntee your transmission for life…ie they will pay like up to 2000 to fix it if it goes. Some people are not a fan because they feel that it can put “pressure” on the trans lines.
Why does my Honda Accord shake at 40 mph?
A warped rotor plate can cause front end shake. To identify wheel balance or tread squirm, rotate the front tires straight back and see if the problem stays in the front. If it moves to the back, it’s a wheel/tire issue.
What causes engine hesitation and stumble problems on the 90 +?
Then it developed an intermittent hesitation problem- you would be cruising at 60mph, on a 400 mile trip, ease off the gas pedal, and suddenly for 1/4 second, it was as though someone had switched off the engine and then turned it back on again. The car would then run faultlessly for the rest of the trip.

What happens if your transmission goes bad at 40 mph?
This problem can develop at any speed, depending on which gear of the transmission is going bad. The engine will continue to rev as the car tries to accelerate above that speed, but the car will not be able to shift into gear for further speed. Continuing attempts to accelerate can result in severe engine damage.
How many miles per hour do you travel at 45 mph?
At 45 mph you are going 3/4 of a mile per hour which isthe same as .75 miles covered so to cover a distance of 1 mile it would take 4÷3 or 1.33 min or 1 and one 3rd min First, convert mph to miles per minute. In this case, we have 45/60=0.75 miles per minute.
Why does my car shudder at 40 mph?
Problem Description. A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter. It is recommend to replace the torque converter and install an updated powertrain control module (PCM) to correct this concern.

Can a car stall with a bad throttle position sensor?
The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.

Why does my car sputter when I drive?
Dear PoppaQ– I could list 25 reasons why your car is sputtering while driving, but let’s start with the most simple solutions first. It may be your fuel injectors. Buy some fuel injector cleaner at a parts store. Run a tank of gas with that and see what happens. I would also check my airfilter.
What to do when your engine is sputtering and losing power?
Be sure to check the rubber boot connectors for the vacuum where it connects to fuel pressure regulator and at throttle body and trans. Mine were all cracked and leaking and not obvious. All of the damage was on the bottom out of sight. I moved them and there it was. Replaced them and problem solved.
Why does my 1999 GTP engine keep sputtering?

Why does my car sputter when I Turn on the engine?
The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
The only issue was that the car would shudder pr even buck a bit ONLY at speeds around 40 MPH and ONLY when the accelerator was backed off of slightly and when an attempt was made to feather the pedal and maintain a steady speed. This was traced back to a light film of corrosion on a coil wire.

Why do I keep losing power on Mikala?
Just think it odd the 2nd to 3rd gear change appears to be same as Mikala’s stuck shift. I use the selectable gear shifting when going up a hill and passing it allows you to hold a gear that way you get a constant amount of power instead of the regular auto that wants to shift down and up at the slightest pedal variances.
Why is my car losing power at low speeds?
If the pressure is low the fuel injectors will not be able to spray the correct amount of fuel into the combustion chamber and that will result in a loss of power. A faulty fuel pump will not pose problems at low speeds but when you are looking for quick acceleration you might be left wanting.
Can a car go bad at 40 mph?
