The po136 code is a bad 02 sensor, on cylinder bank #1
sensor #2, which is the downstream one. needs new one.

Where is oxy.sensor


Usually in the exhaust pipe near the engine.
They don't usually cause a rough idle, and the check engine light should be on if you have a faulty sensor.

Rough idle and smells like gas when driven


When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

Intermittent rough idle on 2002 toyota highlander


before you do this I would get some wooden qtips - the long ones auto detailers use. take off the air filtrer assembly and spray carb cleaner into the air\fuel intake and use the qtip to wipe out the inside of the intake. I had the same problem with my highlander a year ago and this fixed the problem.

Rough idle after check engine code cleared


I would check for any vaccum leaks,
You can take a spray bottle of water and spray around the intake manifold with the car running at idle.
The idle will change and get worst if the intake is leaking.
The intake gaskets could be the failure. I know autozone can get into the computer and clear the codes for free.

good luck
