2000 Nav Running Rough & Stalling. Have Codes:

Hey all,

Have a 2000 Navigator with 109K suddenly running rough and stalling. The first thing I noticed was a low pitched hum sound, seemingly coming from the drivers side firewall area, and then a near stall situation. Now it seems to continually run rough and intermittently give the previously described symptom. I took it to AutoZone and they provided me the following codes: P0131, P0136, P0151, P0156, P0171, P0174.

Any ideas. I'm looking for a good place to start.

Thanks in advance for your suggestions.

Scott

Could've sprung a leak in the intake gasket in the area you're describing.
