asked by on

Just bought car ssanyong rexton 270 deisal drove 135 miles runs fine until you slow down gets back up to 40 takes ages to get off 50 no power

My car has 100.000 miles.
My car has a manual transmission. 2005

Check the throttle pedal position sensor on the gas pedal and see if the wiring is loose or pinched. If the wiring looks good and is not damaged, then I recommend replacing the sensor. If you need further assistance with your vehicle loosing power after letting off the gas pedal, then seek out a professional, such as one from Your Mechanic, to help you.
