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.

 

Would you have to short tyhe terminals on a '94 22RE also??

 

yes. timing procedure and specs are all the same for all of the 22re's.

 

oh. ok thanks for the response.
happy wheelin!
