Having a devil of a time finding a throttle body replacement for a1989 Micro Sprit (Toyota Truck 3.0L 3VZ-E). Except for some awful one's on eBay (eg, rusted and beat up, $200-$300) it's impossible to find a new one. But I seem to remember someone mentioning that they were able to "upgrade" their throttle body on their 3.0L 3VZ-E 6 cylinder with a newer one, a throttle body that's still old somewhat at large (parts geek, rock auto, Autozone, et.al.) Any leads in this direction would be most welcome!
And by the way, can someone please tell me what this part (yellow arrow) is? It's spring loaded, has a boot, but doesn't alway "open up" as in slide open, when the depressor is moved away. Thank you!
