Q: Acceleration Problems

asked by on January 30, 2017

When i push on the pedal lightly the jeep accelerates fine and will get all the way up to 90mph but when i try to accelerate more aggressively and push hard on the pedal it doesn't shift and then starts to slow down and decelerate. The check engine light is on and i want to know if there is an easy fix for this problem or if i have to bring it to a mechanic.

My car has 71000 miles.
My car has an automatic transmission.
