Detailed Application Coverage

This WAI distributor is built for the 1.6L 4AFE application identified by ID #19030-16140 and is located on the passenger side of the vehicle. It cross-references 19030-16140 and 94850028 for the same application. Use DST77416 when servicing a 1990-1993 Toyota Celica, a 1990-1992 Geo Prizm, or a 1990-1992 Toyota Corolla with ID #19030-16140. The complete assembly format helps reduce rebuild time and supports consistent ignition performance in these Toyota and Geo applications.

Common Issues This Part Can Address

• Hard starting caused by distributor wear or internal component failure
• Misfire or rough running from inconsistent ignition signal delivery
• Ignition timing problems related to a worn distributor assembly
• Cap and rotor wear that affects spark transfer
• Service delays when the original distributor is no longer performing to OE expectations

Installation Notes

Confirm the vehicle ID number, engine size, and passenger-side distributor location before installation. Match the existing unit to ID #19030-16140 and verify the connector and mounting layout against the removed distributor. Because this is a complete distributor assembly with cap, rotor, and coil included, installation can proceed without rebuilding the original unit.
