My car technician (or let's say, mechanic) was nice enough to give me a ride home, then pick me up when my car was done. While I was at home, I researched the issue (EGR Valve- Exhaust Gas Recirculation), I found that the part ranged in cost from about $75 to $200. In fact, the part at the Ford Parts Store (OEM) was a little less than what was on my itemized list when I looked at the bill. Hmmm. I hope the installed part was OEM, but we don't know that, do we?
They also cleaned around the area which is good, since gunk has probably built up over the 14 years I've had this FORD FREESTAR van. It didn't take them long to do the work, so I guess I was charged a relatively good labor rate.
I just hate it when the check engine light goes on - it usually costs me between $500 and $1000 to get something fixed. If it starts happening regularly, it would be time to find a new automobile, one that is large enough to haul stuff, but nice enough to drive through $million neighborhoods without someone pointing and laughing.
