Just came back from autozone........Got scanned b/c of my check engine light going on......To make a long story short i go to start up my car in the morning for work and it wont turn over.....Take the beater to work, when i get home i try to start it up again and it fires up right away but the Service engine soon light comes on....Today i take it to autozone and it gave me these 2 codes P0101, P0103.......It says the PCM has determined that there is a discrepancy between the actual mass air flow input and the calculated mass air flow input derived from the input gathered from other sensors.. Throttle position sensor, barometric pressure sensor ect.... the other code states that the PCM has determined that the Mass Air flow input is higher then expected for the current engine operating conditions......... Any suggestions on a fix for this problem.... is it my injectors slacking, or a dirty MAF...Any help before i bring it to the shop would be much appreciated thanks

 

You probably have a dirty MAF or sucked up some water. Check the sensor and see if that solves the problem. Mine problem is the crank sensor just went out so I can't even start my car!!

 

yea.......... my car wouldnt start up at first either, i didnt think the MAF could stop your car from starting, but then it started right up. Hopefully ill have nothing to do tomorrow and will figure this out

 

sometimes taking some electrical parts cleaner (aerosol) and spraying the maf to clean it can work wonders. i did this even when my car was stock and i could tell a difference. think about doing this every 5000 miles for maintenance.
