Don't mess with the timing yet.
Jumping TE1 and E1 will not harm the car.
It'll just put the ECU in diagnostic mode.
That means, any stored error code in ECU memory will show up.

91 is octane rating of gasoline.
The higher the number, the more difficult it is to self ignited.
Higher octane helps prevent detonation.
I'm sure you will do fine with 87 on 5sfe.

OBD = On Board Diagnostics
94-95 6th gen Celica is OBD I
96+ 6th gen Celica is OBD II
They have different interfaces.
If your car is OBD II, you need to use an OBD II code reader/scanner to read malfunction code.
There is a port to plug in the reader under the steering column.
If your car is OBD I, all you need is a wire or paper clip.
