I dont think the Temp sensor is that accurate on the hondas. I mean it could be possible, but ive never seen it but theres a first for everything.

Usually the tach jumping around is a sure fire sign the coil/ignitor is going bad in the distributor, it will work great in the colder weather but when it gets hot, it will act up.

I had it happen once to me, and i know how frustrating it was for it to work 1 second then not the next lol
