Known issues on the 1991 Sonoma. Nothing appears against the 1991 Sonoma in the federal record: no recalls, and no owner complaints logged with NHTSA. What the manual has to cover instead is breadth — three engines across two cab styles and two trims, each with its own service figures. Engine mechanical, fuel and ignition, transmission, brake, steering, suspension and body procedures are set out system by system, along with the torque values, wiring diagrams and diagnostic routines for the 2.5L four and both V6s.
