1996 Deville: stalls..DTC..air flow..filter, fuel pressure controller

Customer Question

hello,
I have a 1996 Deville
Hard staring and and stalls when applying gas.
Did not overheat and there is water in oil or oli in water
The following three DTC's are showing
--pc0102( mass or volume air flow circuit)
--pc0171 (system too lean bank1)
and --pc0174 (system too lean bank2)
Would this be a fuel pump, filter, fuel pressure controller which is more likely? Or something else?
I also have DTC's showing
-- PC1559 (unkown meaning)
-- IP1552(keep memory alive error KAM)
--PZ1558 (BCM eprom checksum error)
-- RF2560 (radio related not certain what) The radio has been removed
Any Ideas on these?
Thanks
Ed

The p0102 is a low air flow through the mass air flow sensor.Make sure the air filter or air filter box is not plugged.Inspect the wiring and connector to the mass air flow sensor.If no problem is found you may want to try a new mas air flow sensor.The low air flow code will also set the p0171,p0174.

the pz1558 is an internal bcm failure code requiring replacement of bcm if the code resets after clearing.The p1559 indicates that an engine stall was detected.

There are no blockages and would the a bad air flow sensor be enough to cause stalling when gas is applied? or are you saying that the BCM is causing the problem.
Expert:  David H replied 5 years ago.
Yes a bad air flow sensor could cause stalling.The bcm failure will have nothing to do with the engine problem.You may not notice a problem at all from that code.
