Late follow up. The CEL from previous post was from tech putting rear passenger O2 in front and vice versa.
I've not been happy with shifting since getting it back, occasional shutter during slow acceleration uphill and shifts just don't feel right. Shop agreed it didn't feel right but wanted more miles on it first, they made a comment about replacing the crank sensor if/when we brought it back in.
Fast forward a few weeks/miles, I run into the monster home improvement store and when I come out the truck starts goes to about 1000 rpms and immediately shuts down. It does this three or four times before it starts and stays running. It didn't throw any codes.
Another week, another mile, the truck stalled while driving in the driveway. Both symptoms in my brain say it could be related to the crank sensor, so I call the transmission shop. After they say this and that about when they "may" be able to fit me in, I replaced the crankshaft position sensor. I left the battery unhooked overnight.
Shifting does NOT seem improved and today it exhibited the 4 starts/dies before running again with the additional stall when stopping in a parking lot, this time with P0102, Mass or Volume Air Flow Circuit Low Input.
I could use some help/direction on troubleshooting. I have limited faith in the transmission shop and I am not certain anything is related to work they have done.
Some points for awareness, I replaced the starter solenoid in this timeframe and I previously installed the Hewitt SAIS bypass.
