Afternoon Scotty,

 I’m back with the 2012 Tundra that would start and then stall. After replacing the MAF, it didn’t help one bit. I took the battery out and put it on a charger for a while (was low from sitting with the 4 ways on and trying to crank the truck over for 3 days while working on it) I tested the battery, full charge, put it in the truck, tested it out again all over the connectors and wires where I could get a connection, everything was fine. It tells me the alternator is charging also. The sensors reset by this time, it was hours after I took the battery out. Started the truck, and it ran like normal. But I don’t think I’m out of the woods yet. I Idled it for a half hour, let it relearn it’s normal idle at 700ish rpms, and took it around the block a bunch of times. No more random dash warning lights. The Only codes are a ‘permanent’ P0102 and P0113 that don’t seem to be affecting the engine currently. However, I was looking at the live data and noticed the LTFT is at -17 at idle and around -10 when I step on the accelerator fairly lightly (I’m in a residential neighborhood). Is this normal? or possibly because it was sitting at idle for a while after resetting all the sensors? STFT is very close to zero in park and on the road. Thanks in advance any input is appreciated.
