Engine Codes.....
I took the car to Advanced Auto Parts today to get the codes checked for free... and well this is what the code ticket reads:
Vehicle Scanned
Global OBDII
Vehicle
DTC (Codes)
P0401
EGR Flow Insufficient
DTC Pending (Codes)
No Faults Detected.
Can some one help me with what this means. The guy there said my exhaust gases were going back up into the engine area? how does that even happen? Anyway does anyone have any better ideas or how to fix it?

Maybe the EGR passage is clogged!
Clean out the carbon and soot buildup in the passage.
The EGR valve goes rarely bad. It's an expensive part, so you don't want to replace it unless you absolutely have to to. Test it.

An electric drill with a piece of flexible wire with a frayed end will work
Shove the wire into the pasage and losen all the builduo. Then suck out the debris with a vacuum cleaner.
Good luck with removing the EGR valve. I tried once and gave up. That sucker is stuck for good!
