have a 2011 tahoe that throws codes p0102,p2161,p0420,p0430 but those items are fine. the reason it throws them is the truck will glitch just within a millisecond. when it does the engine dies for that millisecond, the guages bounce back to start position then back to normal and at the very same time the door locks accuate.sometimes if at an idle it will kill the engine all together, but only at a idle. If up to speed it will keep running but do all the other crazy stuff. what gives?
