So my Moms went to get her old baby Smog Pre-Tested even after I told her not too because I have a buddy that would pass Smog for me as a test.
Welp, she pre-tested it in a panic ( old woman ) and FAILED, EGR flow failure and PCV & Hoses needed changing ( after tester broke it ) Arse-bite. Good news she was running pretty clean. So he wanted to remove intake manifold and see if cleaning out the ports would allow proper flow. I was like WTD? Why not just a TB service and clean the ports in situation ( remove vacuum hoses and ream them out ).
So I picked the car up and and started working on it. YEAP, TB was complete dirty, full of 150K miles of delightful carbon build up and some ports were clogged with carbon ( PCV side ). Replaced what wrench broke with a new Toyota PCV, and Hoses ( Breather too )
Finishing up READINESS DRIVE CYCLE, no more pending code P0401, All GREEN, Just waiting for Cat to do it's cycle. 100+ miles to go.
Bonus, she idles real smooth now, good throttle response and quieter to boot, WTD?
