Hoping someone has resolved this issue… My 01 325i e46/m54 stalled out on the freeway yesterday, acted like I ran out of fuel. I had over a half tank so it was not lack of fuel.
Engine would turn over for a second then quit. I checked all vacuum hoses and air boot after the MAF all were good. I had a fuel filter/ regulator in the trunk, so I changed it. Then re-primed the fuel system, and no luck. I have spark, fuel , and air. I even replaced the MAF, and plugs. What ever is fouled out all six spark plugs (six weeks old).
P0102- MAF Sensor Circuit Low Input
P0171- Fuel System Too Lean (Cylinder Bank 1)
P0174- Fuel System Too Lean (Cylinder Bank 2)
P1083- Fuel control limit mixture too lean (Cylinder Bank 1)
P1085- Fuel control limit mixture too lean (Cylinder Bank 2)
Man, I am at a loss… Any help would be appreciated, Thanks…
