Have a 95 4 runner and to stay idle you have to keep your foot on the gas.What could be the problem.

Thanks

 

Idle could be set too low. Clogged air filter?

It would also help to include engine and trans too

 

Pull codes and see if anything comes up.
What engine?
The Idle Air Control valve may be malfunctioning.


Also, does it outright die? or does it just idle really bad, really low rpm?

 

brake servo vacuum line may be leaking
duct from the throttle body to the air flow meter may be leaking
duct from the PAIR resonator to the air flow meter may be leaking
Throttle position sensor or air flow meter may be malfunctioning
ignition advance (timing) may be set incorrectly
catalytic converter may be partially plugged
...
many things can cause this issue

 

the engine is v6 and is a automatic. vechile is not mine is grandmothers i am going to check all these things
