ID this Blue & Green electric Vacuum Control Please?

Post by Toyotadude »

And what does it connect to? Most of my vacuum lines are wrong because they were missing when I got the car. I just replaced it with a Asian rebuilt carb from out West. I'm only getting 20 MPG.

TD,

The FSM is linked in one of the first “General” stickies and provide some decent drawings for vac line locations. I believe the blue/green part is a replacement VSV.

you may have the wrong carburetor, your '87 T4wd wagon has the same carb as the '83-86 sedan and wagons, not '87-88 sedans: often suppliers will send the carb for the "87 sedan, that is a completely different model, different engine and will not work with the 3ac engine.

there is a vac diagram in a "sticky" posting for the T4wd available elsewhere on this forum you can down load. incorrect routing will harm drivality and fuel economy.
