I have been trying to get this code to go away. My VSC Light off blinks and Check Engine Light will also blinks. I finally got this code. I have swapped coil packs from 1 to 2. And I have replaced all 4 plugs with new NFL. There was a bunch of gunk on Cyl 1 plug.
All four were whitish. I have 193k miles. It uses oil quite a bit between oil changes. I also dumped a bottle of Seafoam in the tank at a half tank and let it run for about a hour. Hoping it would help clean out the injectors. I'm dreading buying a new injector
because they run $137. It will hesitate when giving throttle some times. But at idle and light throttle it's smooth. Help.

You've tested the usual stuff. Next step is injectors. Maybe try swapping 1 & 2 to see if it moves. Also did you clear the ECU after you swapped the coils to make sure it was reading a new code?

yep cleared the code. Well I will swap the injectors this weekend. Thank you

I tried several apps on my phone. Toyosys free finally gave me the right code for an O2 sensor. At 193k you could have another one go bad.
