I
might have a very slow leak, either internally in the EHA or a bad seal. Although there's no smell of fuel, I noticed some gunk on the connectors and on and around the EHA. But there's also some gunk on and around the intake runners so hellifIknow. Don't know if this is EHA gunk or general engine gunk.
I'm assuming that a leaky EHA would not affect current readings?!
Of course I haven't checked my fuel regulator pressure yet which might shed some light on this.
