Vacuum line schematic 1987 toyota corolla le front wheel drive

It is similar to my rear wheel drive two door.

The main vacuum line from a vacuum source on the intake goes to the multi-hose valve on the top and the distributor vacuum advance.This multi-valve switching valve is the main connection to the other vacuum hoses on mine. Two lines come in from a vacuum source and thre go out to three components according to tempature. On mine the middle one off to side 1)goes to choke opener and switching vacumm valves mounted on the fenders the other middle one 2)second from top goes to another choke opener and EGR Valve and EGRModulator. The bottom hose connection is on when cold 3)and goes to a part on the carburator to help it run better when warming up a AAP valve.

There is a check valve diaprham thing inline to the EGR vlave on the second line from top.

I have another vacuum line on the drivers side of the carburator that has a check vlave inline but larger it goes to the throttle linkage to help slow the closing of the trottle on rapid deceleration.

Email me, and I'll send you a picture of my engine bay. I have a 1988 Corolla and it should be the same. [email protected]
