Map change
As the title states, I have been having a problem for a while now that seems to be related to the IAC. I run 2bar open loop sd after driving for an hour my car will run lean. I logged MAP and found at closed throttle in neutral rpm 932 injector flow 11.09 gps IAT same temp. ECT same temp. my MAP value went from 44kpa to 37 kpa and stayed that way. So I went from running a little rich to running lean. At part throttle it gets so lean the car starts bucking. Anyone have any ideas on where to start? I hoping to swap out the IAC this weekend to see if helps.
