<< I got code 23 for pin 8 >>

Code 23 is bad coil secondary..
You are looking for 5.2-8.5k...
I think that was just a pending code from the old coil , but watch for a return..

On your 3 at 14, that could be if you lifted the throttle by hand when working on the engine...

FYI.. the coil primary calls for .9-1.6 ohm spec..............
