Default Running problem

Driving home from a vette meet last night my 1978 c3 auto developed a bit of a problem.
It was dark so lights on etc - the revs held up continually at about 3000 rpm - like a sticking throttle and the rev counter was very erractic often staying on max revs although this was not the case of the engine rpm.
Any clues anybody as it was to dark to venture into last night?

Start with your voltage regulator.

If this happens only at night, your alternator is having problems keeping up with the extra demands created by the lights.
