What causes hesitation when cruising at 40 to 60 mph?
In my case a random misfire (hesitation) was happening every 4 to 5 seconds and was caused by a bad air/fuel mixture (lean misfire) due to the bad oxygen sensor This sensor was causing a rough idle too, after changing it, no more hesitation when cruising and idle became much smoother the link below helped me to test the sensor
What causes a car to stumble on acceleration?
Other problems that cause acceleration stumble include vacuum leaks, low fuel pressure, a weak spark caused by low coil voltage or bad coil (s), retarded ignition timing, and contaminated gas. Look at the following with your scantool (as shown in Figure 7): throttle position, mass airflow (MAF),…
Why does my car hesitate when I step on the accelerator?
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. It is usually the result of a problem with the air and fuel mixture within the combustion chamber.
When does a car misfire at cruising speed?
The misfire is clearly felt at this speed because the torque converter clutch is engaged that means the engine and transmission are considered as 1 unit so any slight misfire in the engine will be felt in the transmission and this is happening only when cruising My advise is to go with the following sequence:
Why are people skipping and hesitating during acceleration?
I’m creating a thread here because I ran it by Andrei and he is stumped now. Imagine at 5:00 in the afternoon, some traffic is merging in from the left, a good amount of traffic is merging from the right, and these two lanes lock up ahead a little ways.
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.
Is there a problem with durring light acceleration?
The truck starts and idles without an issue. Durring light acceleration and at low speeds (city driving 35 mph or so) the truck seeems to run fine. However, when accelerating to highway speeds you notice that the truck will intermitantly jerk.
What does it mean when your car hesitates when accelerating?

When does a Harley Davidson engine misfire at low speeds?
However, when cruising along about 25-30 mph (in either 2nd or 3rd gear) it is always misfiring and sputtering pretty bad now (had a little hint originally and definitely getting worse now). After coming to a stop, the idle is a bit rough and sometimes the engine acts like it wants to cut out for a few seconds after which it seems to idle OK.
