Unfortunately, My van is still running extremely rich..so rich that i have to pull the hose for the aux air valve off to suffice the overage of fuel. Though the aux air valve is working correctly my deductions leads to the fuel regulator. If there too much pressure will it cause a constant overrich condition? I pulled the vaccuum hose off of it and the idle didn't drop nor was there any fuel coming out of the vaccuum port.I also checked the TPS and it's working correctly also the temp2 sensor is functioning as well. The airbox is new.  Anyone ever have a fuel pressure regulator go bad??
