Hi,
Was looking for something else completely when I came across this so thought I would chip in even although the thread is months old
I had the same problem. Looked at MAF, ABS etc etc. I ended up cleaning the throttle body thoroughly and readapting it. Haven't seen the lights since. I presume it was the TB not knowing to what degree it was actually open or closed throwing all the other sensors out of sync. Might be worth a try for you too?
