4.5 L check engine light
Hi...I have an 89 Fleetwood Sixty Special with the 4.5 Litre engine. My check engine light, service engine light and service air cond light all come on, the dashboard flashes and my climate control and fuel data panel go into default mode with the letters "c" or "d" showing. Anyone have any ideas? I have had the charging system checked and its putting out 13.9 volts. Thanks for your help!
