1964 Cadillac AC with a 7 port Vacuum control valve

Is anyone having the same problem I'm having ? In park with AC on no vacuum at the fast idle diaphragm, ( so the fast idle diaphragm is out and bumping up the idle) when I put it in drive I'm getting vacuum there. So in park with the AC on the engine is idling at 900 RPM's put in drive it drops down to 450 600 ish. So when your sitting at a red light it feels like the engine is starving for fuel not to mention it's running hotter than it should.

Best to remove the driver side tire and inner wheel well to help get to the exhaust manifold bolts
Jason has a write up on here as to the best socket to use on an air power tool to get the manifolds bolts off hopefully with out braking bolts in the head making the job more complicated than it might be otherwise

Enjoy

Thats the way to do it, exhaust manifolds are a pain in the butt.

It doesn't end but I love it. I'm having a friend change my drivers side exhaust manifold and oil pan gaskets. Traded some work on the car for some wood off of the sawmill.

Is working fine, now working on the intake manifold

How did you make out with your comfort control system Joe?
Comment by Joe DiIaconi on August 26, 2017 at 1:04pm
I second that request
Comment by Clovis on August 26, 2017 at 10:21am
What changes to the system did the seven port dash control add as compared to the five port? I'm asking this since the shop manual doesn't have a seven port dash control diagram in it.

Hey Joe D

Listen DARLINGS you can call me what you like -just don't call me late for Drinks and Dinner !

A lot of misinformation on this tread at its beginning

The whole idle up thing makes good sence knowing it only happens in neutral and park
I did say that mine has been disconnected for many years ( so no recent feed back from it ) and that i could not understand how the trans torque converter would be effected by the higher RPM In Drive ( not reasonable )
That does not excuse me as i did not realize i really did not know the way the idle up feature really works

I actually learned a lot here about the idle up feature and how it should work from this tread

In reality once again i do not think this idle up feature is at all necessary
The cars RPMS do increase some just by not being in gear and the AC work just dandy without the 900 RPM increase and the additional fuel you will be burning

Anders thanks for your input on the subject and the bottom line Bibles info Amen

Enjoy

   Has anyone drilled the backing plates and made the slots that allow brake adjustments without removing the wheel?  I have always hated the slots in the drums.Continue

Help on Removal of rear seatback on 64 convertible

Posted by Nile Bolen on January 8, 2021 at 11:44am 7 Comments

I'm trying to remove the rear seatback on my 1964 deville conv.  The only help on this site that I can find is the following:

The seatback, its bright stainless trim, and the speaker grille are removed as an assembly.  The seat back hangs on two hooks near the top, and is retained to the body by two bolts and washers near the floor, one on the right side, one on the left.Once these fasteners are removed, lift the seat back upward and free it from the hooks

I've removed…
