Injectors are bleeding off after shut down, or the engine is running extemely rich, or incomplete fuel burn due to bad plugs, wires, etc. This is serious and will do damage to your engine. Get this repaired ASAP

Also check the fuel pressure regulator. The diaphragm may have ruptured. If there is fuel in the vacuum hose to the regulator you have found the problem

i had an 84 with that problem it was the fuel pump.the pump is located in the driver side of the block and is pushed by the mootor. my pump was warped and did not sit right it caused gas in the oil
