Good advice. I'll dig in more. Just pulled codes again. They were: P0101, P0131, P0151, P0332. Thanks

I agree it's probably something basic. I'm just not well versed in troubleshooting newer vehicles. I thought maybe the logs would tell something to someone who knows how to interpret the information...
Ok. It may have been a little lower (54 maybe). Not sure. I thought it was supposed to like 65. It definitely started spitting lean codes right after the fuel pump change. I assumed it was lower than...
Truck is stock. I did take the PE x1.05. I'm an old newbie. Don't really have a handle of VE/spark tuning. I changed the fuel pump and it caused it to run real lean. The fuel pressure on the new pump...
My 2004 Sierra 2500HD has been spitting codes and running poorly. Mainly spits P0101. But also misfire, knock sensor, 02 voltage low, etc. I have removed torque management, etc. But no fuel or spark...
Ok. Will do. Exactly the kinda of tips I need.
Also thinking forward about getting a wideband. I guess I would need to weld in another bung (or two?). Or can you run the wideband in place of narrow band for tuning full throttle then switch back?...
Here's the log from my first "real" drive.
Yes, it was a cold start log. I took it for about a ten mile drive this morning. Everything looked and felt good. The idle is a tad bit low.
I have watched a ton of videos. Still haven't done my...
It turned out that I had the wrong o2 sensors. Don't know how I managed that. Lol! I got them early in the journey. Lesson learned. Put new ones in and it's working perfectly. Fuel trims are almost...
You're definitely onto something here. The sensor voltage is already added to my default scanner channels.. I looked at a log file of my truck and it's reporting it there. What settings should I look...
Shouldn't I get a code if the sensor voltages are off? I don't believe I have reporting turned off.
Ok. Would that mean bad sensors or wiring problem? Sensors are both new. Maybe scanner not set up correctly? I'm using the default scanner setup.
It looks to me like it is adding fuel at idle thinking it's lean when it's really rich. I don't think I have any exhaust leaks. I do have ball and flange collectors. Could it be leaking some oxygen...
This morning I started it with the MAF disconnected. It started and idled fine. Shut it off and connected the MAF. Started and idled fine. I had been disconnecting the battery each evening to be safe...

Newbie to late model tuning needs help here. I just got done converting my ?64 GTO to LS platform. I bought a high mile 5.3 with harness and PCM from a friend. I stripped all the electronic trans,...
