cammed 99 5.3 olsd, 226/232 113lsa 95# fic injectors with there data. my problem is only for a couple of minutes after start up (hot or cold) my afr is richer than commanded and i believe its causing me an idle issue because most of the time i have to stay on the throttle to keep it running untill it leans out to commanded afr. After idling for 3-4 minutes the afr climbs quickly (5-10 seconds) to commanded numbers. the only thing i can find is people saying the ve table is off, but it never switches to any other ve cell when it goes from rich to commanded. It likes to idle in the 800rpm and 60-65 kpa cells, and wile never leaving those cells, it goes from -11% for the first few minutes after start up to +-3% for the rest of the time the truck is running. turn the truck off and restart then it goes through the process again no mater if its hot or cold. olfa table is set to 1.0 after 50*
I've spent a lot of time looking for a solution but I'm having no luck
the below log doesn't show the transition from rich to lean because i ran out of time, but it shows it commanding 14.2 but running much richer.
