I’m looking for advice testing and fixing stored and permanent codes. Truck is a 2013 Serria 2500 6.0L Vortec with 283737 miles. I have P0420 P0430 and P2097 codes using my live data I see both upstream and downstream sensor are fluctuating high and low is that defiantly saying the cats need to be changed ? Also P 2097 bank 1 high limit keeps coming back trying narrow down cause I will attach photos of freeze frame when code occurd some live data photos thank in advance

Hi All, First post on the forum here so let me know if more info is needed. Was recently putting a new set of headers on the truck and decided that at 200k+ miles, I should replace the starter. My hope was to avoid having to pull the headers when it did eventually go out. I purchased a reman of the OEM part (GM Genuine Parts 323-1637 Starter, Remanufactured). Part went in no problem and I also replaced the heavy gauge wire to the battery as well as the smaller gauge wire to the ignition switch. All was functional for the first week or two, when I turned it over and got nothing... No clicks, but the battery had power, dash lights looked good. I hooked a power pack up and it started no problem. Thought it was a fluke or I left a light on, but after having a no-crank condition maybe one out of 15 times that I start it, there is definitely something going on. Here's the weird part... every time that it does not start, I eventually get it to start with no changed conditions. I've tried starting it in neutral which worked the first time, didn't work the second. Another time I screwed with the battery terminals and it started, one other time I just sat there for a minute or two after no-crank and it started. Battery tested fine but havent taken a multi-tester down because it's been starting anytime I am home. Any ideas?

What would be the best way to go about getting rid of all the clatter on cold startups on a 2008 Silverado 5.3L, and what would need to happen to get rid of the 4 cylinder mode all together?

Help with 06 Sierra 6.0 liter gas, Getting a P0430 code on my "Ancel AD410" code reader, and No OBD2 scanner reading for short term fuel trim bank2/2 just _ _ _ I tested before Cat and after Cat temps on bank 2 with only a +30 degree f. diff at second O2 sensor. Where or what do I check to find the problem with the "short term fuel trim bank2/2" and is that why I get the P0430 code?
