17.8-18.9 AFR @ idle, thoughts?
I have a message to Kevin @ CSU too, but I thought I would see what things you guys come up with so I can try to resolve it.
Carb is currently set with idle mixture screws about 4-4 1/4 turns out! I know its alot and Kevin said the same thing too, but less than that and the car was around 19.7-20.5 AFR.....
I have checked for a vacuum leak, there is none. I went as far as unplugging the Boost Reference for the fuel pump, MAP, etc. No changes to idle or AFR, went back and plugged them back in 1 by one with new hose and still no change..... I pulled the hat off the carb and plugged the 4 air bleeders on the carb itself and the idle sounded rougher (by myself so was not sure officially), and did data log and AFR went down to 15.9-16.5....
Does this mean metering block? Anything else I can try?
