My Chevrolet Tahoe had a flashing service engine light come on. The truck started to sputter. I brought the car to the dealer who tried to clean the fuel injectors. He had to replace the injectors. After I got the car back, I started to notice a gas odor in the cabin. It appears to only happen when the car is warm. If you start the car, turn the heater on and let the car run for approximately 20 minutes, you notice the gas odor. If the car is moving, you do not notice the smell. If the car is stopped at a traffic light, you notice it again. I have this car back to the dealer 3 times and they can not replicate the problem. It only appears to be noticed when the car is running and heater is on. Hopefully, someone can offer some advice that I can share with the dealer upon my return.

It's possible that you have a fuel leak at the fuel lines where they enter into the upper intake manifold. If the retaining clamp was installed upside down, it can cause an intermittent leak.
