Ae82driver

Hello everyone, first time posting on the forum. I came across this thread, I have an Ae82 that has suddenly developed the exact same intermittent starting problem. Ignition timing varies as if the ecu forgets where TDC is on starting. Takes a few attempts to start. Either way too advanced or retarded. And sometimes starts first time with timing correct. Tried swapping the ecu, coil and ignitor aswell as the distributor. Same issue. Has the member that started the thread ever found the problem?
