I have a 2005 equinox lt,and my problem is it cranks fine and take off fine but when i accelerate pass 3rd gear the gas pedal lose engine power and a triangle light with down arrow pop up and speed drop down to 25 mph with foot to floor. But when i stop,light goes off and it drives fine until after the 3rd gear cycle and repeat the fault again. TC light and triangle light pop on. I have real bad hubbearings,can this be the issue of loss power mode kick in?
