P0175 TROUBLESHOOTING

1997 Ford Expedition

Engine problem
1997 Ford Expedition V8 Four Wheel Drive Manual 310000 miles

Folks, the mileage is in Kms.
The Truck has been awesome.
Codes have plagued me during the last 2 years. Go figure with the mileage.
Anyway, all Coil packs, Injectors, Fuel pump in tank, O2 Sensors, and MAF Sensore has been replaced, and now I'm getting a P0175 Trouble COde.
In reviewing this site, I have kicked my own ass, as I fear that the K & N Filter I put in the truck two years ago is now the culprit.
The only other thing I can think of is a Vacum leak, which I am at a loss to determine how to check/pinpoint the leak.

Any ideas would be most welcome.

Cheers

Neil
