It could be your MAF sensor. Mass air flow sensor that measures the air going into the intake. This could likely cause sluggish acceleration.
A bad fuel injector.
That is a standard feature on all Frontera's.
Your car can run sluggish and have problems starting
Slow engine RPM is the main reason a car may be sluggish while accelerating. However, it also could be due to the oil.
Many things can cause a car to be sluggish like dirty air filter, check engine light came on, bad transmission, bad engine, etc.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
try the fuel filter.
Sluggish 7 unresponsive.
No, if a car is slowing down, its acceleration is negative. Acceleration is defined as the rate of change of velocity, so if the car's velocity is decreasing, its acceleration is in the opposite direction.
The car with the highest acceleration capability in the table is the one with the fastest acceleration time.
check your fuel filter.
