Ok update: I have the wideband O2 in now. First off, up at high rpm WOT i'm not leaning out at all, I'm in the 10.8-11.4 range(if anything i'm a tad rich). When i installed my new wideband (AEM digital) i set it to P4 and wired it to my CPU. Here is the very stange thing now. she is showing very lean 15.8 to ---- when coasting to a stop, and just doesn;t recover very well, stalling now as i get to stops every 1 in 3 to 1 in 4 times. This is worse then before. I keep throwing fuel at the main fuel table in the 400-1200 rpm (where she starts to stumble and die) in 2% increases with very little change. Is there a table I'm missing to turn "the coasting fuel shut off" off at certain RPM? Also, once warmed up, her idle is 550-650, 100-200 rpm lower then before (ideal idle set to 750 in the system). Any thoughts?
