Nowhere. The '98 cannot be timed like the older trucks/engines can.

This vehicle has a distributor cap and a rotor. It is not electronic ignition.

I have looked by the firewall and by the computer but can not find it.

Timing is still controlled by the ECM even though you have a cap/rotor.

The computer is on the pass side under hood - see all the wires by the AC housing. Timing determined by all the sensor inputs and PCM/ECM then adjusts.

The distribitor is set with a scan tool and the spec is 0 degrees.Look for cam sensor retard in the data.You run the vehicle for a second and shut it off.

You can turn the dist all day and not change the engine timing.
The dist cam retard setting is for centering the rotor to fire dead on the plug wire terminal.
