1990 Isuzu Amigo Service and Repair Manual

Open-air fun was the Amigo's whole pitch, and for 1990 it remained a two-door convertible with a soft top over the rear seats, offered in S and XS trims. Buyers chose between the 2.3L and 2.6L SOHC four-cylinder engines, and each has its own ignition, valve and fuel-system specifications, so knowing which one you have comes first. This factory service and repair manual covers the 1990 Amigo with step-by-step procedures, torque values, wiring diagrams, diagnostics and maintenance schedules, keeping your work matched to this exact year rather than a generic multi-year summary.
