About ford windstar engine codes Sign In

I have 1999 Ford windstar and my check engine light is on. There are three codes showing up they are p0171, p0161, p0174. Could anyone tell me what the codes mean? Thank you..

 p0171 - bank 1 too lean
P0161 - low voltage bank 2 sensor 2
P0174 - Bank 2 too lean

lean conditions could be vacuum leak, Low fuel pressure.

The O2 could be wiring open or O2 it's self. Don't think the Bank 2 Sensor 2 would cause it to run lean. Usally after cat O2 are just used to monitor car performance.

My dad changed the spark plugs and wires cause it was reading that the cylinder four was misfiring. He had first hooked the wires wrong and I bought a book for it then he changed to the right way (so he said). Could he have something during the process of all this to cause these problems?

maybe he knocked a vacuum line loose while working on it.. also famous for coil packs if your miss is not fixed.. you should have the pack visually inspected for cracks.
