I have a check engine light code of P0174 (system to lean bank 2). Does anyone know what this means? Thanks.

In most cases it's a vacuum leak. It could eed intake gaskets and bolts and the PCV hoses. Cleaning the MAF often helps. In most cases, P0171 will show up too. Here's some information on them. 2000 Ford Windstar (Codes 171 and 174)

vaccum leak, mine was on the lower prot seal on the lower half of the intake plenum. Dorman makes a complete kit part # 615-177 that has new Valve cover and gasket, port seals(6), TB gasket, IAC gasket, isolator bolts (8), intake gasket(where the upper and lower plenum split. i just got done with mine, pretty easy.hope that helps!!
