can any one tell me where i can get the duramax service manuals for cheaper than $200?

 

i got factory service manuals that cover all trucks within the year that i specified, good enough for me. ill give you a link when i get back form work

 

What does the P0401 code stand for

 

Code: P0401
Modules: ECM
Description: Exhaust Gas Recirculation (EGR) Flow Insufficient

 

yea p0401 is VERY common after doing a bigger exhaust, or EGR blocker plate... Finger stick can fix it, or you can use the PPE Programmer, or EFI live to hide the code..


Danny, can u PM me that link for 07 Classic LBZ FSManual? I would greatly appreciate that..

 

these are the kind i got

 

I just learned about this too the other day, but if you look under "Bomb Site" up top, at the bottom of the list it will have a link to check for DTC Codes.... It is very fast!!!

 

what is finger stick? and where can i get the ppe programmer?

 

Finger stick is what deletes the EGR code when you block it

 

Does your link cover lbz? If so can you pm me the link as well?
