Over the past few months, my series 2 E type has had intermittent misfiring issues with running. The car was off the road for 8 years and was back on the road a year ago. I had SU carburettor issues sucking air from areas they shouldn’t so I rebuilt them. I’ve replaced spark plug leads, coil, condenser and the issues seem to improve initially then develop again and worsen. Today, I drove approx 60kms on a motorway at 100kph and it developed a misfire. I got almost all the way home before it died and I had to have it towed home.
Once home, it wouldn’t start or run so I checked and found the spark from the coil is very weak. I disconnected the spark plug leads and plugged a spark plug in the ends and the spark is very weak.
The coil, spark plug leads and condenser were all replaced a month ago. The points look fine and are not burnt out. I don’t have a ballast ignition. It is the standard Lucas distributor.
What are your thoughts? I am totally stumped and the bloody car is stuck in my driveway because my garage is at the top of my steep driveway.
Thanks in advance for all your help.
