INTRODUCTION

Note. Monaco and Premier models are manufactured with either an early or late design. Only late design models are covered in this article. Late design models are equipped with DIS, with engine controller (SBEC) located next to battery. Service procedures for early design models, with engine code Z7X711, are the same as those found in 1990 DOMESTIC SERVICE & REPAIR

Note. Shadow and Sundance Convertible models equipped with 2.5L TBI engine are manufactured with either early or late design fuel, ignition and emission systems. Late design vehicles use an epoxy ignition coil, mounted on thermostat housing, and a high pressure fuel system requiring quick-connect fuel fittings. Early design vehicles use an oil-filled ignition coil, mounted on right inner fender, and a low pressure fuel system using hoses and clamps.

Use this article to quickly find specifications related to servicing and on-vehicle adjustments. This is a quick-reference article for when you are familiar with proper adjustment procedures and only need a specification.

WARNINGOn the 3.0L V6, the firing order and the spark plug connection order on the top of the distributor do not match. Circuits internal to the distributor cap differ from the external spark plug wire connections. This is intentional and is done to avoid spark plug wires crossover. (Scheme 4)
