P0401 - Insufficient EGR flow (usially means vacuul leak in EGR engagement or dirty EGR valve).
P2C59 - ?? Are you shure? Codes ends P1xxx...
P04E0 - E0 - can't be, according to SM by Ford.

wow ok...so I took it to two different places only code was the EGR code, not to worried about that don't have one, but the car still has a hard time with cold starts. I also cleaned the MAF, seafoamed the gas tank and engine and did the fuel filter.

If you illiminate the EGR system wihout the "chip-tune" this code will be anyway, it will become your best friend and will always lit up your CE lamp. It can become a problem, 'cause you will not be able to determine visually, what codes do you have, and will have to read codes regulaly to ceap you car healthy.
And I really don't know (and the Service manual don't) what the other two means...
