Trouble code P0320 means: Ignition Engine Speed Input Circuit Malfunction

Crankshaft Speed sensor should be replaced.

p0171 is a lean condition for the right passenger side of the vehicle bank 1 on vehicles with rear wheel drive v6 or v8.

    A lean p0171 condition can be caused by a vacuum leak, bad or dirty Mass Air Flow sensor,
    bad EGR differential sensor (DPFE).

I got a diagnostic test on my car cause my check engine light is on and it is shaking real bad when driving it and when i stop at a red light it seems like it wants to stall out


P0305 is a # 5 cylinder misfire , do you know what that is ? Check engine light flashing indicates a severe misfire that can damage the catalytic converter . Don't drive this vehicle ,take it immediately to a qualified repair shop or the dealer .
A Ford P0171 is a LEAN code for cylinder bank 1, and P0174 is a LEAN code for cylinder bank 2. These codes commonly occur on many Ford vehicles, and are set when the powertrain control module (PCM) sees the air/fuel mixture is running too lean (too much air, not enough fuel).
