Ok I recently rebuilt my s14 sr I got everything new in it and it was running fine. I just installed the split fire coil pack set up, aem wide band eugo a/f ratio gauge and aem try boost gauge. It was all running fine untill all of a sudden the a/f ratios started tripping out first it was rich as hell 10-11.5 the car was bogging and dying out and that lasted about the day and the night came and it was lean as hell all of a sudden 15-16.5 at idle but while driving it would richen up to about 12-14 and now it's just staying lean as hell at idle 15 + and staying about the same while driving wtf could it be?
