I meant the maf flow was 5.86, the fuel trims go anywhere from -7 to +7 usually 0 sometimes, and fuel pressure is 33lbs so thats good

Look at this at idle

Ok there shouldn't be a 5% difference between banks and both of those look high at idle. I'll check mine this afternoon and see where it is but the last time I had over 15% at idle I had a hole in the elbow at my pcv valve.

I'm not seeing any code. The trims still have 5% between them. May be an 02 issue but you are under the threshold for throwing any code. Will it idle in park at all or does it just die after slowing down?

I can't shake the idea that this is iac related. When you shift out of park into drive does it die?
