Detailed Product Overview

WAI DST1803 is designed for drivers and repair shops replacing a worn or failing distributor in late-model GM performance and full-size applications. This distributor supports direct-fit service on 1994-1995 Buick Roadmaster, 1994-1995 Cadillac Fleetwood, 1995 Chevrolet Camaro, 1994-1995 Chevrolet Caprice, 1995 Chevrolet Corvette, 1994-1995 Chevrolet Impala, 1995 Pontiac Firebird, and 1994-1995 Cadillac Commercial Chassis vehicles. The unit is manufactured with all-new components and tested for long-lasting performance, helping restore consistent ignition timing and dependable engine operation.

This part cross-references 1103916 for the same application. The WAI DST1803 is a practical OE-style replacement when the original distributor shows wear, signal issues, or internal component degradation.

Common Issues This Part Can Address

  • Hard starting caused by distributor wear or signal inconsistency
  • Misfire conditions related to weak ignition timing control
  • Rough idle from deteriorated distributor components
  • Intermittent engine performance from a failing optical distributor assembly
  • Cap and rotor service needs when replacing the complete distributor

Installation Notes and Tips

Verify engine application and distributor indexing before installation. The cap and rotor are included, and the ignition coil is not included. Because this is a complete distributor assembly, it is intended for direct replacement service on the listed Buick, Cadillac, Chevrolet, and Pontiac applications. Confirm connector routing and timing setup according to the vehicle service procedure before starting the engine.
