Known issues on the 1984 Seville. One recall is on federal record for this model year. It covers the vehicle speed control system: a small nylon bushing in the cruise control servo bail can slip out of place, causing intermittent and unexpected increases in engine speed or dieseling, and the servo rod assembly can catch on engine components, resulting in a stuck throttle with the potential for a crash. Owners have filed 1 complaint for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind that system are here.
From a cruise control inspection to routine service work, it keeps you on the OEM procedure and the correct specification for your specific 1984 Seville.
