Can anyone help me figure out what this code means? I took it to autozone and thats the reading im getting --

Their device said Manufacturer Control - Fuel Air Metering

I thought 02 sensor but the guy at a-zone says no.

Oxygen Sensor System too Lean Fault Banks A & B - so this means i need to replace a hose? which hose?

thx
PCV hoses (breather hoses) at the rear of the engine.

A vacuum leak in the system will throw all other sensors out because it assumes it is a sealed system....

Replace both hoses - there is a third running from the bottom of the cyclone back into the sump, just check that to make sure it's OK, if you need to replace that it's easier to buy a new cyclone at the same time.

You may even see an MPG increase after fixing them and a smoother idle.

See here for info:

It's an easy, but messy job that's well within the scope of anyone who can use a screwdriver... You're basically just taking two hoses off and putting two new ones on, not difficult at all. Mine was made more complicated by the fact that some of my LPG pipes run over the top of the engine and got in the way a bit, I also didn't buy the genuine hose (as it will just dissolve again). Any autofactors should do hose, you want 19mm internal diameter hose - one end is 21mm so you have to soak that end in hot water to soften it up to be able to stretch it.

All in all, you'll need 2 meters (overkill but incase you cut the first too short etc) of hose and 4 new jubilee hose clamps (buy a 5th because sometimes you get a dodgy screw)

Not sure if I could be more explicit there really, unless you want the exact address? Perhaps re-read the information I have given you, and look through the links provided and read the posts in detail.

All the info you need is there, by all means if you get stuck, just yell.
