My check engine light has been coming

My check engine light has been coming on-will stay on for a day or two or three at the most and then go off for a while. This started in December, happened once-happened again in February. This month it has been on more than off so I finally went to have the codes checked. The Tech pulled code: P0 0401 EGR Flow insufficient Further diagnostics are needed. (OUCH!!!) Any suggestions before I open Pandora's box and my bank account? Where should I start? Like many people, I am paycheck to paycheck and will need to budget for any major expenses. I am not mechanically inclined, but do know several people who are. I have a couple of road trips planned soon, 700-1000 miles each. Other than fuel economy am I going to hurt anything by not having this fixed right away?

Hi there,

The first thing to do is get a scan done as there is a set fault code in the ECU. This i feel will not be associated with an electrical problem, this may well be a faulty alternator, i would get the charge rate checked and also inspect the battery terminals are clean and tight, start here.
