my uncle has a 1989 volvo 744gl and it sputters and sometimes stalls when acellerating from a stop. sometimes when the car has been sitting for a few days untouched, it will be hard to start. cap rotor plugs and wires are new within the past year. when i do an obd code check it gives the code 311 which means the speedo has no signal, but the speedo works fine. i checked the wiring in the trunk and under the car and behind the dash and all is fine. what could it be? ecu fault. the car hasa 240k on it.
thanks in advance
