Ford Edge Sport 2013 Lack of Acceleration

[OtisLee]

My Ford Edge doesn't seem to want to accelerate after a few minutes of driving. When I press the gas pedal, I get nothing. I have to get off and on the pedal again to get the car to give it a little acceleration to get me down the road. The cats were replaced two years ago. I have changed the ATF fluid, cleaned the MAF and throttle body, and replaced the air filter. No check engine lights. However, I did plug in my Bluetooth scan tool and noticed that the TPS didn't seem to be responding to my gas pedal. I can pretty much tell when this problem is happening; it only shows that the tps is reporting a split second spike to say 40-70% throttle, then immediately hits 15% throttle and won't budge, but maybe 1 to 2% higher or lower. What should my next step be with diagnosing? replace the trottlebody??

If you have a capable scan tool, you may be able to do a throttle relearn function. The teaches the throttle body the travel parameters of the accelerator pedal. And Calibrates it. You could have a faulty TPS sensor as well. You can start by removing the air intake assembly so you have visual access to the throttle body blade. Have someone help you by turning the key to the “run” position and without starting it, have someone press and depress the accelerator pedal and watch the movement of the throttle body blade. To see if it’s moving properly. And also have them hold it he pedal halfway down and hold it there and see if there’s any twitching or movement of the throttle body. To make sure the throttle body is working correctly. Also check the condition of your throttle body’s interior. Make sure a it’s not gunked up with carbon deposits or dirt. If it turns out your throttle body isn’t responding correctly then it’s most likely going to need replaced. You can also pull the harness from your throttle body position sensor and do a resistance test with a multimeter. Check to see if the resistance is changing with the movement of the accelerator pedal. But have visual access to the throttle body’s interior and blade to check its behavior when the gas pedal is depressed. Car must must be in “run” position but not started to do this. Hope this helps
