I have an 08 IS250 55k miles and I drove it yesterday and it drove fine and this morning I start the car and get down the hill and when I approach the stop sign the car like loses all power it started stuttering and it felt like when your about to kill a manual car, and then check vsc light comes on and CEL starts flashing. I pulled it over and it was idling real hard so I turned it off for a little and then it didn’t start! It took me a 3 times to get it to start and then I drove it home. As I was driving it home it felt like there was no power in it. Can anyone please help me diagnose this problem? I would really appreciate it
