Over the past two weeks I have done a few tests for the engine in my 84 Lucas. All the coolant, air, and throttle position sensors are at the correct spec. The lines to the Map sensor seem to be in good condition. The plugs and wires are new with a good blue spark from the coil. The injectors have been cleaned and new fuel lines with good fuel are installed. I have checked the mechanical advance as per Kirby’s book and all is well.
However, I find that I am still having major problems somewhere in the system. Backfiring and a reluctance to rev at cold temperatures still plagues the car. My last guess would be the o2 sensors. Is there something I have forgotten to check?
