Customer: replied 5 years ago.

the 2005 es has a electronic thortle body so when I remove the TB is wasn't

like on a older rx 300. I got car back together and runs but the check engine

light is on. Check the hose connection only see a hose fit on the rear valve cover

that does not have a hose. I am not sure if there should be one there cannot seem to

a loose hose. any susjestions.

Is the vehicle running ok? If you disconnect the battery to clear the engine light does the light clear?
Customer: replied 5 years ago.

the engine is missing at idle speed and seem to run smooth at 2000 RPM>

the check engine light does not clear if you disconnent battery. I think I disconnented

hoses and unbolted intake manifold and throlle body may have leak or mass air sencor is not working.

Expert:  Tom replied 5 years ago.
Ok that's the issue then . You will need to go over your work and reattach the vacuum line and make sure the mass air flow sensor is connected. Once you go over your work you will find the cause . Hoped this helped. Positive feedback and bonuses greatly appreciated.
