my 5sfte is running rich at idle. I have to take out 30% of fuel with my safc in order to get the 13-14.7 ish a/f ratio.
set up: 255 lph pump 440cc injectors everything else is stock What could be causing the problem???? could having the engine retared to much at idle be the cause of the ecu not being able to adjust to a rich mixture????? This post has been edited by urbandork: May 15, 2006 - 12:15 AM |

why are you so worried about being rich at idle?

This happens less when i take out the 30% of fuel and more if i dont and keep the car running rich. |
