My car is a 1987 Toyota Tercel DX Wagon 1452cc 2bl manual driven car.
It seems now it doesn't have a TVSV, Thermostatic Vacuum Switching Valve. I need it to activate the AAP Pump and the Choke Pull Off.
Can I add any TVSV valve commercially available?
What is the location of the TVSV valve in my vehicle?
