idle problem with 2016 Diesel Prado

My 2016 Prado has a intermittent fault with idle speed. When the engine warm up the idle speed in Park is 1000 RPM, I put it in Reverse the speed drops to 650RPM and same in Drive. After driving a short distance, I might need to stop at traffic lights. The idle in Drive, with foot on the break goes up to 1000 .Then when I go back to Park its 1000, I have had all the sensors checked , including the MAF and IAT sensors, they are ok. I added some injector cleaner to the last lot of fuel, and the problem went away. Now I have topped up the fuel , (30 litres) and the problem has returned. Could it be a dirty DPF or is it a Diesel fuel problem. Any ideas appreciated. Thanks
