Been quite a while since I last posted.
I have a 1980 TR7 soft top with a 3.9L-V8 transplant, electronic ignition and a GM 1-wire alternator. Been running fine for about 10-12 years. However....
Recently, she started having problems. She will start and idle fine with choke when cold and for a short while without when warm. Within a few minutes of driving, the turn signals stop flashing and the engine won't idle. If I keep the rev's up, she stays running. If I let her cool down for an hour, sometimes whatever is wrong resets and she is fine again for a short while, but sometimes it doesn't reset. If I disconnect the battery and reconnect, whatever is wrong is reset and the cycle starts again.
Even when the signals won't flash the 4-way flashers work (Yes I know there are separate flasher units), headlights work and will pop up. Fuses all look fine, but I changed all of them to be sure. I'm sure it can't be coil or dissy 'cause that wouldn't affect the signals, would it? I've examined the wiring and short of pulling the dash (again), I can't find and shorts.
All thoughts and suggestions welcome. Help!
