ON this car the overvoltage relay is working if the idle is correct & the "lamda" frequency injector is buzzing whenever the engine is running.

well they tested the car with the computer..and it was flat line.. they changed the O2 sensor and that didnt work
one mechanic thinks its the fuel frequency valve and the oil temp switch.. another mechanic seems to think its the OVP relay..another one thinks my cadaltic conver is plugged... my oil dash gauge is bouncy benzat 1982 380 SEC
