Have an ‘08 Sienna XLE. had all these random misfire codes (VSC) and even would have to shut my van down as the “traction control” light would blink along with the engine light causing the van to lose power and decrease in speed, till I shut it off and restarted it. And that would take care of it for a week or so then back again, usually one the Highway. So off to the shoulder again as the van would slowly lose power and buck and gas be basically unresponsive Seems like maybe the compression was changing over the 200,000 miles as i started putting premium gas in and the higher octane was the key.. as all the codes went away (once cleared) and never came back. Same spark plugs. I did change one injector (before I switched to premium gas) as it did have that code come up for the number 2. But the check engine lights would still come on. But same spark plugs on all 6 cylinders as those back are just too hard to change without a good reason. Again premium gas and all my check engine lights and blinking lights are a thing of the past and it’s nice having a dash free of those. (Those lights came on probable a dozen times in the past. But now problem solved for like 9 months now and counting. So if it returns might try that. I’ve disconnected my battery several times. And light always would return after a period of time. Also I had cleaned my gas cap in the past. But premium gas is what helped when everything else was just a temporary fix. God bless

You're great👍 sir

@@klujics123 Back then I've bought ODB2 reader to show me the codes and it was coolant thermostat stuck in in opened position. So on highways, especially in the morning, cold air ventilated radiator really well, which lead engine to be much colder than it should have been. Computer saw it and check engine together with VSC (not clear why VSC but whatever) came on. After I replaced thermostat (myself, not a big deal if you have a long wrench to deal with tension pulley), I cleared errors and it never back again.

@@kovalenkoihor4325 thanks for the reply/ update… very interesting to hear what the issue was. Food for thought.

What happens if there is no code after reading OBDII but VSC light is on? It happens to my T Sienna 2009.

First!
