I had my car tuned about a week ago. The 2nd day after the tune the LTFT's started locking in at 5.3 when they are supposed to be at 0 like they had been doing. So i replaced the fuel filter since i had finished my first tank of e85 and disconnected the batter for 20 minutes. Reset the trims and they were locking at 0 again. Today as i was going to work, i got on it once and they locked in at 0. But at lunch i was coming home and got on it again and they were only locking in at 2.3. Whats the deal with them not locking in? Every now and then i will get blips of KR at like .2, .4 and .8 once but nothing higher. My wide band reads a 10.1 A/F and my o2's are at 950s. The guy that tuned it said the A/F is normal for running e85. help would be much appreciated.
