Update: I got my vehicle back
Update: I got my vehicle back on July 3rd. It started having acceleration issues again the next day after 80 miles. Dealer sent a tech to pick it up. They’re not sure what exactly is wrong, as I am only the 2nd person they’ve seen with this unique code. Could be a computer issue, could be they used the old O-rings in the new pump, could be the fuel rail... so they are attempting to diagnose. Back without a car and skeptical on ever getting a Lexus again.
