Hello all,
Brand new to tuning anything. I just did a mechanical DoD delete on my 2007 Avalanche. I left the VLOM sensor plugged in, and on start up, I get the following codes:
P3449 Cylinder 7 Deactivation solenoid valve control circuit
P3441 Cylinder 6 Deactivation solenoid valve control circuit
P3425 Cylinder 4 Deactivation solenoid valve control circuit
P3401 Cylinder 1 Deactivation solenoid valve control circuit
Makes sense right? Idles perfect but the truck is in limp mode and will do like 5mph max. So, I purchased the MPVI3 and turned disabled the DoD, wrote the file, then got the P0171 and P0174 codes saying lean on bank 1 and 2, as well as a very obvious miss at idle and the stabilitrak message. I rewrite the stock file back in, and it idles fine again but has the cylinder deactivation codes again and back into limp mode.
Why would I get a lean on bank 1 and 2 code with the DoD disabled and not when it's enabled? I'm at a lose as I really want this truck back on the road.
