Hole near O2 bung / down stream
Hole near O2 bung / down stream
7302 ECM
wonder how that has effected the tuning, found a inch long, 1/4in wide hole after the O2 bung down stream so it should of been heated ok, yet revision could have sucked air in.
that why it has smelled fat rich for a long time, also the source of the mystery exhaust tick/leak I could never find...?
