Cool P1371 code DI low resulution

I did a little research and it could be either the crank sensor mounted in the timing cover or the optic sensor mounted in the the opti. Car was running fine I just happened to notice the light and I scanned it. Car is not driven since its January I just happened to start it.

P1371 Distributor Ignition (DI) low resolution circuit
Opti or opti harness. It's not the crank sensor.

Does it take longer to start? Last time I saw a low resolution code was on the LT1 my Mom owned, car took forever to crank, but it ran alright. It was the opti in her case.

Cool

No actually started fine. I was surprised the light came on. Where can I get a new opti harness? I have replaced the opti before twice. Before I pony up the bucks I would like to replace the harness. At least if its not the problem it will be new.

I got my last one for $35 shipped... But the damn clip that holds it in the opti broke the first time I tried to pull it out...
