still more 90tq advice needed

[ed armstrong]

Hey folks,

I thought I was making progress with this beast but
I've still have mucho problems. There is still smoke
coming from the car even after an extented warm-up and
the spark plugs are always black upon inspection.

Things improved when I removed the bypass valve from
the system by clamping the valve inlets and outlets
shut. There is now a steady idle, but the car misses
and hestitates on accleration. I actually leaned out
the CIS mixture one turn and it helped the idle
somewhat but still smokes.

I've tripled checked timing and vacuum connections and
everything seems OK. Removing the dip stick or oil cap
briefly affects the idle so I think this should
indicate that there are no air leaks (?). The air
sensor plate has nice smooth action and does not seem
to stick. I haven't checked the spray pattern of the
fuel injectors but they worked so well on the original
NG engine I can't see them being bad, They have new
seals. Once thing I also noticed is the carbon
canister solenoid clicks like crazy but no check
engine light comes or anything like that.

What really concerns me now its that there is black
oil dripping out the downpipe (exhaust is not
competely tied together yet). Where could this come
from? Are the turbo seals shot and could this affect
mixture (I verfied that the donor did not smoke at
idle when I first bought it)?

....I've never seen a I-5 run this bad, the car can
barely drive 100 yards! Mike, wanna come by next
weekend and have a go at it ;)
