Most likely the problem with gas in the oil is the fuel pressure regulator. When they leak, gas goes into the vacuum line and causes a flooded condition. This can make it hard to start, ssputtering, stalling and a check engine light. Get it fixed as soon as possible or you will damage the engine since the oil is now contaminated and dilluted.
