tricks of the trade more,
an illegal TB base gasket. made by you.
seen here,
steps
TV 109% closed (99.99% or set it just under 0.001" inche gap, I have feeler with 0.0005" and use that. until later all runs perfectly too slow.
1: tb pulled if 3speed car, it has 2 gaskets, one is below the intake heater and one on top.
make a gasket and for sure 5 holes blocked per normal.
2: but now block IAC hole

I made a good one by hand here, so make one like it but IAC hole blocked. doing so makes engine starts impossible with 0 air. so use 5% right foot throttle to start engine.
as you can see with TV closed there is ONLY 1 path for air, and tha tis IAC bleed air port , below and the vacuum port ARC seen below, you can block both, do that then cut the arc, , see what happens on both. there and not there.
