Thanks Arthur for the tip. I have checked the fuel pressure regulator as you mentioned. I pulled the vac line and let it idle for about 5 minutes and nothing came out. I turned off the engine and let it sit with the vac line off and still nothing.

This morning I cleared all the codes. It takes about 2 days for the CE light to come on. I will report back after 2 days or earlier if it comes on again. Thank you for all your help.
