My apologies for posting this here but I did not see a "Windstar" category. I have a 2002 Windstar that is running rough at idle and while driving. This occurs while the vehicle has warmed up and when cold starting. I stopped by my local garage and they pulled the following codes but I do not where to start. The following codes are listed in order they were pulled: P0174, P0304, P0122, P1504 & P1401. I have replaced the coil pack approximately a year ago along with plugs and wires. Anmy help would be greatly appreciated! Thank you.

 

The Windstar is also a 'van' but has nothing in common with the Aerostar. Different engines, transmission, etc. The Windstar is basically a Taurus with a van body. You can find the code definitons online almost anywhere.

I understand but with that many codes any ideal where to start first? I have a list of the codes already just not sure which one to start with.
