Default 7MGE on Toyota won't run with air intake snorkle detached

7MGE on an '89 Toyota Cressida - I was going to shoot some throttle
cleaner into it while running hoping to clean the throttle and idle
air control valve but find that the car won't run period without the
air intake snorkle assembly in place. Is that the way it is with this
engine? Apparently it needs the vacuum the snorkle creates? Or does
this indicate a problem? Sure different than my '66 Ford 289 which has
no problem running sans air cleaner.

Thanks

Is this an injected engine? If so, that's normal.

The MAF is in the intake "snorkel". The MAF expects airflow. Disconnect the
intake pipe and there's no airflow. No airflow means no fuel delivery.

Older Hondas also do just fine without the intake pipe attached. Those
engines use MAPs instead of MAFs.

If that has the vane style air meter I'm thinking of, we used to prop
them slightly open with a stick, to simulate an "idling amount of air
flow" allowing the engine to run while the TB/Intake cleaner canister
sprayed into the TB. IDR how thick it was.
