DTC Code 0380

My LB7 keeps sending the 0380 code every time and everyother time i start er up. I keep having to delete it with my programmer, but now its becoming a pain in the aZZ. Sumthing with glowplug feedbak? Any Resolves for this? Buddy with a LBZ having the same problem.

If it is a Federal emisisons LB7 that code is form the glow plug control module, most likely starting to take a crap. If it is a cali emisisons lb7, it will be 1 or more glow plugs.

probably won't warranty the emissions with a 5" straight pipe but you could try.

They cannot deny your warrenty due to modified exhaust. They can try, but theyt cannot prove that your 5" exhaust f'd the controller..
