Throttle body cleaning
Hi all,
I have cleaned my Yaris' throttle body some 50,000 km ago so it is probably time to do it again to keep hers 2SZ-FE running smoothly. So far I have been always doing it in the way that I put ingition key to "1", pushed gas pedal and I used throttle body spray cleaner and a rag to remove the dirt. However, the throttle body has been always connected to the engine so I cleaned only the visible area. I have read a few articles that it is actually good to unbolt the throttle body completely off the engine and to clean it comfortably outside, on a desk. From both sides. 1. Do you have any experience with it? Is it really just a matter of 3-4 bolts and a few connectors/hoses to get the TB out? 2. How do you open the flap when the TB is on the desk? AFAIK I cannot operate the flap by hand for drive-by-wire systems. But the flap edges are actually the most critical (and most dirty) parts. I guess I need to connect the wires back and use the throttle pedal to open the flap? 3. Any torque specs for screwing the TB back in? Thanks folks. |
