svx eg33 Bank 1 negative long term fuel trim -12% to -16.8% while driving was created by subarumike25rs
I have a 1997 svx EG33 engine installed into a 2006 forester, everything is working great but while driving i have a high negative long term fuel trim on bank 1 between -12% to -16.8% and when idling it becomes more stable at -1% to -2%. Bank 2 seems to be operating normal. Any help would be appreciated!
