I have a 2016 Suzuki escudo(vitara) I had a bad cooling fan then after that and I started to get a heavy idle and a loss of power when reversing up inclines. It doesn't move at all but on flats it does reverse. I have replaced the cooling fan so far, the throttle body so far has been ruled out. Another problem is the car heat meter is a stroke or two above half which suggest the engine may be getting too hot. Can I get help?
