Ok, so ive been was having a problem where my truck would flood if it sat idleing too long. recently it started flooding out when I turned on the head lights or even the dome light. the alternator is charging at 14v and I'm getting 13.3 on the back side of my isolator (dual battery setup). this system has been inplace and working for 3 years. both batteries test good and fully charged. I'm going to look for a loose ground tonight. I always thought it was funny that it would run a bit rich at night. could this be an issue with the injector latency settings even though I haven't messed with them other than copying the ones from the vehicle I got the injectors from? anyone have any ideas if it isn't a grounding problem?
