      Too lean bank 1 and 2.
      Work done…. Manifold sensor cleaned
      O2 sensors changed
      Plugs wires and cap
      Iac cleaned
      Exhaust work
      Fuel filter and lines
      K and n air filter
      Variable intake control arms. *** will open but not shut
      Gramit ring
      So here’s what it does… Only at idle hot or cold the van will shake and try to stall
      I’ve been doing most of the work myself I’m not a mechanic.
      Just want this engine light out to pass etest.
      A new mass flow sensor is my next step. Then replace upper and lower intake gaskets.
      I don’t know what else to do. Every other mechanic has something different to say.
      Any advice would be great. Cheers

        Running poorly and dying at idle sounds like a big air leak to me.

          Replacing parts is not a diagnosis. Also, the code is for a lean condition, that does not mean that the O2 is bad, it just means that the O2 has detected a lean condition. That said, you may want to look for vacuum leaks. More information here.

            Make your next step the intake manifold gaskets before the MAF sensor. Also make sure none of the vacuum hoses on the back of the intake are collapsed and leaking. There is also an updated plenum if it’s still available from Ford.

            Those areas are the most common for vacuum leaks that cause a P0171 and P0174 on a Windstar. I have done about a dozen of them over the years.

              So I had smoke test done. The guy hooked the machine near the back of the motor near the firewall. Smoke came out from the fuel filler neck. Would this be my problem? Causing a lean bank 1 and 2.

                I’m a bit confused on what was done. You can check for vacuum leaks using this method. You can also use water if you’re not comfortable with carburetor cleaner.

                You might also want to check for exhaust leaks near the O2 sensor.
