Troubleshooting an Engine that Stalls at Idle When Warm ...

tune it up. (fresh spark parts work best in cold and for sure damp wheather.
fresh gas?
leaking injectors?
isc stuck closed, and rpm low, hot?

the ecu, anticipates the next cold start,
it knows how much to open the iSC valve, to get a good start cold
and if colder to day, it opens more. (math)
if it (ISC) is gummed up,fas all do, it cant start right
so next time, try %10 throttle, starting, emulating a good ISC.
see?

there is problem with relay PGMFI is under left leg.

check if the air intake is clear , no cracks/split etc in the pipe work , air filter is clean,if look ok then i'd get the stepper motor checked out as a first step

Sounds like the starter solenoid on the starter has failing contacts, and needs replacing.

I would need more info on the 96:
when you say struggles to start do you mean it cranks for a long period of time or does it sound weak when cranking.

On the 94:
It very much sounds like the idle control motor. Usually if you let the vehicle warm up in place you can avoid this. take the idle air control off and see if there is a lot of carbon build up and clean carefully.
Most often I opt for replacing the idle control motor.

Remember if this helps, please leave feedback and vote. Thank you and good luck.

iwould check the selector motor,and also replace the thermostant,start with the stant first,the selector motor is what runs the door for hot or cold the motor is a common problem,if the temp gauge is showing a quick warm up temp then its the selector motor, if it takes a while to reach operating temp then replace the t-stant,also make sure the coolant is full in radiator,check when cold or warm,dont open when hot, hope this is helpful.

very common change the temp sensor for the computer. it thinks it is warm when it is cold and doesn't inrich fuel like a choke would. causing to have a hard start. good luck

Check fuel pressure, and regulator. A leaking regulator gives a warm engine more fuel [ it does not like it] a cold motor does. same as a flooded motor. Good luck

if the idle goes up and down constantly it will be the iac motor which is common on hondas
