Yes these are also caused by the oxygen sensor. When the bad oxygen sensor reports the wrong reading back to the engine computer, the engine computer then decides to dump extra fuel to try and correct the false reading, with to much fuel being dumped on to this side of the engine, it makes it misfire because there is to much fuel. Replacing the oxygen sensor on the manifold near the radiator will correct all the codes.

Thanks, ***** ***** bought the car and these codes popped up on the drive home. I will change the sensor and see if the codes clear.
this is all covered with my free trial right? Really want to thank you.

Yes make sure you buy a Denso brand sensor, any other brand sensor will give you problems. They are actually available at Advance Auto Parts, as well as Toyota dealers.

Sorry, I'm not sure how that works, I don't deal with any of the billing or memberships, just deal with the car side of it.

Good luck if you have any follow up questions please don't hesitate to ask ,I would be more then happy to help.
