IML: 66 Imperial IDLE Quality

[mjusten@xxxxxxxxxxx]

Hi Everyone

 

I bought a 66 2dr Crown over a year ago from southern California.  It has always had a 'Poor Idle'.  When you turn on the A/C, it's awful. Short after the purchase, i installed a rebuilt compressor, new receiver/drier, and new expansion valve.  The air is working well now, but I don't like using because of the idle. 

I just took a compression test and all 8 cylinders were between 140 and 150.  The carb was rebuilt just prior to my purchase.  I have recently done a full tuneup including plugs, wires, points, and condensor.  Recent dual exhaust also.

The engine takes off great and accelerates well. Runs COOL, doesn't ping, other exhibit any other performance issues.

This car has the CAP system.  I have by-passed the system and still can't get any improvement.

 

Any suggestions?
