Question Help Please

Ok so i have this 2001 rx300. AWD about 85k. No aftermarket parts.

Just recently the CEL, VSC , and ABS lights came on.

I notice when i turn on the car it idols rough and i have to give it gas so it doesnt shut off. After about 20sec it will remain on. And now it shifts funny between 2nd and 3rd. at first though it was transimission, but i had disconnected the battery just to see if the CEL light would come back on (which it did). the car was running normal no jerking between 2nd and 3rd but after about 10min of driving it happen again. I did have the codes check and i received the 1130 code which is bank1 sensor1 can this sensor be the cause of whats happening? It did have a sludge problem which Lexus cleaned up about $2k It just seems after it was done all these problems occur. I check to see if any air was leaking and all hoses were connected. Any thoughts?

Thanks

sounds like your air/fuel sensor is bad...
