So tonight I started my car just to move it for someone who was blocked in and I tried to start it up and it idled very roughly and shut off. Then after a few more tries came to life. Then, while it was running, I looked under the hood and saw some smoke coming from the engine bay which normally isn't that odd because of my large oil leak but I don't think this is related. I also smelled a strong odor of fuel and the idle sounded off the whole time it ran. Any ideas?
