You know it's very strange, From one minute to another.
I got out of my car and it had been idling at 14/1 afr and then got back in 2 minutes later and had 12/1 afr restarted. This system is simple, no overboost switch, one 044 pump. I feel like it's a system voltage issue because the higher/lower voltage could change pressure from the pump. simple CIS!
Earlier today after 30 minute sit time the idle afr qas at 17/1! On boost it's normalish. When lower afr like when cold the part throttle afr's are super rich and causing stumble and flat power. But when afr's are onpoint...........whew at 1 bar all is well my friends. Problem is that I cant drive full throttle everywhere
Someone tell me why my afr's on an otherwise good running engine might act like this? Voltage regulator?
