156 loss power, fuel injector light
My year 2000 156 twin spark selespeed owned since new, has the ongoing issue of the well described phenomenon of complete loss of power at low speed, onset of injector light, and resolution by turning off ignition and restarting restoring normal function. Initially problem resolved by applying an elastic around the potentiometer connection plug, but now despite cleaning, cable tying and even change of potentiometer the problem persists(? Less frequently since i got it back from mechanic few days ago). Is the connection the problem and Is there an ultimate solution. Mechanic has suggested soldering the wires or thinks it may be faulty ECU and ultimately changing this. I am worried this is an insolvable problem. I would be grateful for some help.
