Hi Everyone, been quite a while since i have been on here.
I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.
With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.
I've had the car dyno tuned and they told me I need a higher stall RPM Torque Converter as they also could not get the car to run smooth enough at the recommended idle RPM.
Here in Australia i run 98 Octane and i installed a "smooth Idle" mild cam when rebuilding the engine. This was all purchased from Cad Company in Albuquerque along with the rebuild kit.
Until now i have assumed that the higher idle required is due to the the fuel i am running over here.
Any thoughts or suggestions?
