Inspect all your rubber hoses and boots and replace any that are suspect. Rubber deteriorates over time, especially if subjected to heat and oil and gas, and it can be difficult to see the tiny cracks. You may also want to replace your rubber fuel lines as preventative maintenance. They are also prone to leaks that will cause gasoline odors and possibly a fire. Also try cleaning your ICV valve and inspect your cold start valve, which is known to be problematic.
