We were trying to get my car running a little better tune wise after I got my big 16g in, got home and it started acting weird. A check engine light popped up and started idle surging. I tried looking for sensors being unplugged and blown couplers, but nothing seems out of place. So I unhook the battery and let it sit for a minute then hook it back up. Still doing it, but I tried taking it up the road and it's at about 10.0 AFR and won't go (obviously).

The car is running on a 2g maf, so I pulled my buddy's maf off and hooked it up. It idles high now, around 1500+rpms.

any ideas or tips? if I need to post a mod's list, I can.
