I talked to Holley today and yes a bad O2 will drive
it fat.. I have one coming tomorrow I hope.. plus now I
one have the learn mode on... I cleared the one fuel
table and its running SLIGHTLY better.. but I dont get
any fuel change on the learn table... also I dont know
if it matters but I have 1 O2 on the right bank and the
left bank was turned on..right side wasnt.. the holley
guy didnt think it mattered but I swapped it over..
it automatically turns on the left side
