    Re: why was AFM taken off the 3.9L

    i was hoping they'd use the AFM in the Lucerne since it's gonna have the 3900 standard. This is the first time that the 3900 will be a standard engine in a sedan. based on the amount of v6 lucernes i see driving around it seems like a great choice for GM. Here they are with a torquey v6 with excess production capacity and its been using the 4T65E right from its debut, and the G-body cant accept any of the 6 speeds.

    I'm glad I bought mine when I did. AFM was the sole reason for purchasing this engine in mine. IMO, this is a bad move on GM's part.

    Well, it's not a deletion...maybe some 3.9L are built without AFM?

    I didn't see any indication that a choice was going to be allowed for the model. This smells of decontenting to me.

    Thats what I was thinking, i'm pretty sure impalas with the 9c1 option (cop car) have the 3.9 without AFM.

    Afm?
    There will be a 3.5-litre V6 version next year, for idiots to buy. Why would you want that? It's like popping into the dragon shop for a pet and coming out with a poodle.

    9C1 and 9C3 Impalas are built with the LZG (E85 capable, AFM 3900 motor). Interesting news, however, and a decision that doesn't really make sense to me.

    No it doesn't. That said, the new engine code for the "regular" impala shows the new engine code for the 3.9 engine without AFM.

    Re: why was AFM taken off the 3.9L

    I remember a little while back when the Lucerne was announced to be including the 3.9 liter, that Flexfuel was going to be optional. I wonder if this is also the case with the Impala, or whether they are having problems with the AFM controller in general. Either way, this would be a feature that I would most definitely want in any car right now to save whatever gas is possible.

    Seeing that I help put the motors into the vehicle, I think I know what motor goes into it . LZ4 for LS models and PZEV models, LZE for LT models, LZG for optional LT, LTZ, 9C1 and 9C3, LS4 for SS.

    I know that the new 2009 V6 3900 engine code will be LGD. I just don't know why it doesn't have AFM. It retains VVT and FlexFuel capability. I did not notice if the Lucerne has AFM, but I know the G6 doesn't, and I don't believe the minivans have it, so this may be a way to consolidate the 3900 lines at Tonawanda a bit?
