Hey its been a while since i have been on here but i have an issue.... I went to long island with my girl last week. I left my car at home and when i got back it wouldn't start. the battery was almost dead. not completely, i could unlock my doors. anyway, i trickle charged the battery and started the car. i took it to work last Saturday and it ran great. it sat Sunday and Monday i drove it to work. Monday after i left from work, the car ran super lean. I have no idea what the deal is. i have been dealing with this issue all week long. for some reason it wants to idle at 16. it wants to cruiz at 16.. i have not tried to boost. i am a little hesitant on that.
so this week i cleaned my maf sensor.
unhooked the battery and let the car sit over night.
i could go in and really crank the fuel, but that wouldn't solve the real issue i would think.
on a side not the weather has been all over the place.
so any ideas would be great.

 

Are you running an AEM FIC to control your fuel management on the vehicle?

 

yea i am running a fic.

 

Loss of power from your battery more than likely whipped out your AEM FIC tune or messed up the file. Re load your tune, sync the FIC and you should be good to go!
