simple sensor or connection could be bad.
EFI is about inputs/outputs...and checking them one by one on older EFI systems (pre OBD-1)
For instance, with a good coolant temperature sensor verified with ohm meter, warm it up to hand temperature, then on a cold morning...hook LH's electrical plug to it, ground CTS out to battery, then start engine on a cold day. A simple test....that informs LH that engine is warmer than engine's block, which decreases fuel amounts
LH's CTS increases in ohms with increasing coldness. One could measure ohms at LH's wiring harness by removing harness from its box, then measure ohms at pin.
Either LH is dumping more fuel than is needed, or an injector is pissing away, 24x7x365.
