Question about 1996 Ford Explorer
My Explorer seems to be having trouble Starting once or twice a day. When it happens you have to release the fuel pressure from a valve on the side of the head. My check engine light is on due to a Faulty or dirty O2 Sensor. Could the O2 sensor be the source of my problems?
Sounds like the fuel pressure regulator is going bad...this will cause the fuel pressure to be high and create a flooding condition. Which in turn will gas wash the motor and contaminate the O2 sensor with excessive fuel. Check fuel pressure with a gauge at the valve you are using to relieve pressure. You can find pressure specs on-line for that particular vechicle. If pressure is high...replace regulator, O2, change oil and reset computer by disconnecting battery for ten minutes...
