My Versa has been having this problem for a while. Sometimes is unresponsive when I press the gas pedal. It seems as if it tries to accelerate, but is unable to. I can press the gas pedal all the way down, and the car runs very slowly. When you press the gas pedal, is as if when you press the gas pedal when is turned off. This issue happens intermittently, so I have been able to use my car like that to go to work. My uncle is a mechanic, but he can't figure out what is wrong with my vehicle. He disconnected the ABS from my car, and I was able to use it without issues like that when the issue happens, but I put it back on because I wanted to see if a code appears to help diagnose it better since it puts the computer out of whack if I disconnect the ABS. And apparently, it is a bad thing to do. Any response would be very appreciated. Anything that can help me figure out what is wrong with my car.
