Okay ----
I have an isue with my car.
I currently have the vacuum advance hose connected to a ported vacuum source on the carb. My TCS system works as designed. I do not have any signal at idle and don't really start to get a signal until 1400-1500 RPM.
When I am driving in 4th gear around 40 -50 MPH ( 1600 - 2400 RPM) I will get a slight surging. Once I do any type of accelration it goes away. If I am driving at a faster speed where I am more keeping the gas pedal with pressure I don't have any issues.
If I disconnect the TCS selonoid the car is smooth at all RPMs and vehicle speed.
Is there a special way to set the initial advance with a TCS equiped car?
Current Configuration:
1. I currently have it set to 8 degrees advanced with no vacuum source.
2. The vacuum lines are attached to the carb as they were when I
bought it. It had a 45K miles untouched engine/compartment.
3. Engine has a high volume/pressure oil pump
4. Distributor has stock mechanical advance plate, weights and springs.
5. Vacuum advance unit on the distributor is new 436-20 (NOS).
---- car acted this way even before I rebuilt the engine and used the new oild pump and NOS vacuum advance unit. -----
any help is VERY appreciated.
