Re-assembled, TB 2' bores cleaned (again), idling OL @ 750...

...awaiting CL.

PLEASE - let's bury this thread...

I KNOW that the Cruise lope was the vac leak at the under-plenum vac connector........

Only the hesitation was the original issue here...

Showing CL @ 138 coolant temp ??? Heat on 90'; heater fan pegged...

Still idling 750, 153', CL, should be lower with pump load for automatic tranny...

I bumped up the throttle; she wouldn't drop back down below 1,400.

^&%*

Shutdown; tried to work the throttle, it was stuck. Broke it free, fired it, and the went right up to 3-4krpm's. Shutdown. Binding somewhere here...

Pulled the accordion, and the primary is stuck open.

???

Closed the primary, and she's got a swing - 750 - 925. IAC readout '0'.

Thought the fouled secondaries might have been the answer, but apparently I DID blow TB re-assembly here...
