hey on my 2000 tl i have 3 check engine lights

-intake air temp sensor high input
-idle air control valve
-auxiliary emissions malfunction

the first 2 came on when i installed thermoblock spacers and cleaned the intake manifold. the 3rd came on when i added seafoam to the throttle body a few weeks ago. any ideas?

 

How did you add seafoam to the throttle body?

We use the intake manifold VAC line that runs along the driver side fender

 

yeah thats the vacuum line i used
