16 - W/jumper wire connected between ALDL connector terminals 1 & 3. The ALDL connector is located under the righthand side of the instrument panel. If a large fluctuation in reading is present raise engine speed to 1500-1600 RPM.
17 - W/jumper wire connected between ALDL connector terminals 1 & 3. The ALDL connector is located under the righthand aide of the instrument panel. If a large fluctuation in reading is present raise engine speed to 1500-1800 RPM. Adjust by loosening & turning cam angle sensor.
18 - W/timing connector disconnected. The single wire timing connector is located in the passenger compartment, under side cover located near left foot of driver.
19 - Rodeo.
20 - Stylus.
21 - EI (Electronic Ignition).
22 - Timing not adjustable.
23 - On models which experience cold stumble, a service modification can be performed. For additional information, refer to Technical Service Bulletins.
24 - On models which experience stalling at idle during cold or humid weather, a service modification can be performed. For additional information, refer to Technical Service Bulletins.
25 - On models which experience an intermittent check engine light & erroneous trouble code, a service modification can be performed. For additional information, refer to Technical Service Bulletins.
26 - On models which experience engine backfiring, a service modification can be performed. For additional information, refer to Technical Service Bulletins.
