Pull the vacuum hose from the fuel pressuer regualtor and check if it has gas-also could be the oxygen sensor or the coolant temperature sensor stuck in the open loop mode giving fuel when not needed-

If it continues it will ruin the engine cylinders/washed out-check your oil if it has gas

no gas in the vaccuum line.
I see that there was no coolant and when I add some and after a while its gone and its not leaking and i dont think its the head gasket either but the oil is really black and smells like gas . How do i test the O2 sensor if it works ?

Thank you so much

Double check the injectors if its leaking and also if the fuel return line is clogged causing excessive fuel pressure.
