car started stalling when revs under 1000

doing sixty last night and car shut off

vdc has come on check engine and check tire all came on

when driving car will turn off engine under 1000 rpm

pull codes and report back

p2a03
p101
p101co

The first one is for O2 sensor, the 2nd is for MAF and the 3d one I am not familiar with. I would start with the MAF, but also check for vacuum leaks.

i took the car to pepboys after 2 hours they suggested i change the mass air sensor , just bought a hitachis MAS and installed , lets see

ps they didnt charge me for the work

How's things now? Any more codes popping up?

so i installed a new mass air sensor , all good friday drove to pennsylvania saturday 100 miles ran great no problems 80 on the highway

sunday went to drive home stopped at a red light check engine came on then the vdc came on as the revs went below 500 seemed like it was chocking.

stopped refilled gas and drove home no problems til i ht the holland tunnel check engine came on and vdc came on at low revs

i drove the car in L gear as this seemed to stop the cutting out of the engine

todays codes are P0101 and p0172

I was about to say check your intake air duct AKA rubber boot between the air filter housing and the intake, but P0172 is too RICH, not too LEAN which would be expected from a vacuum leak. Out of ideas.
