I have the same fault it says Manufactures Control Air Fuel I think it has something to do with the fuel cap since I think the original is vented and mine is "vacuume only" I reset the code and drive around for hours no code but as soon as I turn off the car and restart it the code is back I am waiting for a cap from GM will post if that fixes it.

Got the cap but have not had time to see if it worked but the gm cap is similar in design so my hopes are not high I also replaced the fuel filter as it appeared to be the original one.

Today, I took my car in for a smoog check, it failed with a obd fualt code:P1250 Manfacturer specific code.

I expected it would failed because the check engine stays on. I don't know what the OBD fault code represent. Can someone tell me what that code mean? I drive a 1998 BMW 528i.

I found this same similar problem I had a blow out in my right rear where all my evap hoses to my auxilary fuel tank is. I fixed the hose the only problem is that I can take the car only around the block seeing I can't pass emissions. The code has'nt came back at 40 miles per hour. Could be your problem also seeing this hose is plastic actually two of them down there covered by a hard plastic inner fender. The hose was a beast to repair because you have to be careful not to break the new hose when your replacing it behind the gas filler cap.
