Strange data what does it mean?
I was looking over a log that i took while my car died. All data seemed all right except for a few columns.
-MWFAI -This is eratic with only 0's and 64's
-ALCLMW -Eratic 4's, 20's, 36's, and 52's
-ACUMFUEL -Eratic on and off #'s 0-255 (Very low just before stall)
-ACUMFUEL+1 -Eratic #'s 0-255
-DISPFLOW+1 -Eratic #'s 0-255
-NEWRFPER+1 -Slightly eratic
-ALDLCNTR -Slightly eratic
What do these column headings mean? I know i have a problem with the car this data seems fuel related maybe a fuel pump going bad?
If anyone would be kind enough to look over and possibly give a suggestion to why it stalled i would appreciate it very much. However i don't know how to post the .csv file here
Thanks in advance

The ecm is going thru all it's anti stall strategies, trying to save the motor, and is in a panic type mode.
You need to see (if possible) what lead to all this.
