The plenum seem like the one on my 88 vette that I just gave to my
sister.The cold start should not be an issue it you plug it somehow, Maybe
the 89 gaskets will seal it off. I don`t know what the triangle cutout is
for. I gave all of my repair manual to the new car owner.

Hi group:
I have an 88 conv. that is suddenly running strange, starts
right up and runs at about 900rpm for about 2 secs. then
dies. It will do this a couple of times, then it will start and
run at around 6 to 900 rpm (hunts) with a problem taking
any throttle until about 1/3 throttle, then will take off.
as it warms up the problem seems to get a little better but
it is never right, with a flat spot at small throttle openings.
No light or codes associated with this, thinking maybe
coil (there are occasional backfires when trying to give it
more throttle).
Any thoughts on diagnosis or similar problems greatly
appreciated!
TIA Dave G.

Just a thought...it may also be your throttle postion switch.
