Q: Issue regarding acceleration

asked by on

When accelerating, the car is stuck at (around) 2 RPM's and I am stuck not fully accelerating, it just bumps as if I am going over several speed bumps. It does not happen every time I drive the car but about 95% of the time. I was told it was a transition belt issue, or to put 93 gas in it to clear the tank. Would like to know what to do next?

My car has 49000 miles.
My car has an automatic transmission.

The model, year, and engine would definitely be helpful in diagnosing this problem. If it is a newer vehicle, then it is most likely going into failure mode due to some internal failure with the car’s computer and a computer scan should indicate a code that will help with diagnosis. Other possibilities for acceleration problems include defective fuel pumps, clogged fuel filters, or dirty air flow sensors. If you want to have this done, a technician from YourMechanic can come to your car’s location to inspect your acceleration issue firsthand.
