Well I am now throwing these codes as well. I just got back from a 4 hour drive, stopped home (turned off for a minute) then ran back out to town and just driving normally the car started to stutter and I could not get it to run for more than a few seconds afterwards. Currently sitting in my garage after having it towed back home
Going to take the front bumper off tomorrow to check all the connections for the FMIC as it behaved like this when one of the hoses popped off in the past.
Edit: Ok, freaking out a bit less now. The car idled fine with the MAF unplugged and when I went to disconnect the top pipe of the FMIC setup to get to the MAF to check it I realized the hose going down to the FMIC is loose (as in off) and flopping around. So tomorrow I was planning to take my front bumper off anyway to check the wiring for my fog lights which stopped working a few months back anyway
Glad it happened close to home and not earlier in the the day when I was 100 miles away.
