Engine Stalling
#11
Had a similar problem with mine recently. The relevant codes to this problem are - P0103 (MAF sensor High Output) -
this affects P0171 (bank 1 oxygen sensor too lean)
and P0174 (bank 2 oxygen sensor too lean),
Changing the MAF sensor should cure all these codes and cure the stalling.
The other codes - P0112 (Intake Air Temperature Sensor circuit 1 low) may have an effect on stalling.
P1590 = AC/heater air temperature control switch open circuit
and P1884 Engine coolant level lamp circuit short to ground) I think have no relevance to the problem.
My thoughts - change the MAF sensor and I think all will be well - then clear the codes and scan again after a few miles running

Its the lack of coeds that is the big problem. I found that you can un-mount the Crankshaft Position Seensor (CKP) and even disconnect it while the truck is running and there will still be absolutely no codes generated
Today I though I made some progress when I found the CKP cable was possible loose. After reconnecting I got a full day of driving and idling. However around 3:00 pm after an hour of idling it had stalled and was hard to restart. That one did come with an O2 sensor code P0154
I am going to check the CKP sensor connection again once it is cooled down.
Re: Mass Air I did mess with that and got a bunch of coeds but it did not stall the motor!!!
I mentioned in another post that it would be interesting to find out exactly what it take to put the ECM in shutdown mode.
