timing adjustment procedure according to FSM
hi all,
I was thinking about adjusting the valve lash in my 88 4runner cause i feel it might be a little noisy. (i know the 22re is sounds like a tractor).
so i thought i would check my timing before I did it, just to make sure its not way out. (i have not checked it yet, as i just bought the vehicle)
then i ran accross this in my fsm.
the fsm states to time the 22re:
1. install timing light.
2. let engine idle
3. "short terminals T and E1 of the check connector"
4. read and adjust timing to 5 degrees btdc at idle
5. then disconnect the shorted terminals
6. re-check timing and it should be 10-14 degrees btdc.
Does anyone know why/ what the shorting does?
just curious.

the shorting removes the electronic advance of the distributor. It takes the place of removing the vacuum lines from a mechanical advance that is found in the carbed motor.
