1985 Mazda RX7 Two Wheel Drive Manual 160000 miles

I'm looking to keep my car running good, should I change my injectors, with this many miles on it? My son has the same type call and it floods after he turns it off. I was told it was the injectors not closing fully after the engine was turned off. Any truth there?
Do you

Could be

When the pump is turned off or stops running, the system should hold residual pressure for several minutes (look up the specs to see how much pressure drop is allowed over a given period of time). If pressure drops quickly, the vehicle may have a leaky fuel line, a leaky fuel pump check valve, a leaky fuel pressure regulator or one or more leaky fuel injectors. Low residual fuel pressure can cause hard starting and vapor lock during hot weather.
