190E gas smell from exhaust
190E '88 2.3 8v. I have lately begun to smell gas when the engine is on, especially in cold mornings. To be a little more exact, the smell seems like unburnt "crude" gasoline that indicates a rich mixture. I can smell this odor with the windows open but I never never smell this with the engine off, only with engine running. The smell is not too bad, but I can notice it and ask my relatives and friends if they can smell it. Most of the time they say no but a few have complained that my car smells when runs.
Besides a rich mixture, what could be other causes? Oxygen sensor bad??? a leak in the fuel delivery system? Any ideas on unburnt gas smell while car is running will be appreciated. |

I wouldn't worry about the situation. If there's something wrong, you will find out on your next emission test. When was the last test and how did it do? Duke |
I agree with both post, could be a O2, sensor.
