C3 Distributor advance issues?????

[Tim anderson]

This dist. is all electronic advance (1981). And correct for the car. (not a centrifical unit !)

To set curb advance I unplug the computer connector. 5 degrees simple enough right? But if I rev it up to say 1500-1800 rpm, the advance jumps to 10 or 11 degrees. ????!!! (still not pluged in to the computer)

End play has been tightened up with new and thicker shims but no change. ????!!!!!

Where is the advance coming from????????

Thanks

Manual or automatic Trans?

Bill, This is a 4 gear car. And I'm confused about why this is happening.

I'm not certain either, and it's been a long time (since '81) that I looked at one of these. You are disconnecting the 4-way weatherpack connector correct?

If you don't have it, I can send you the diagnostic chart for this system. Please email me offline. I tried to email you but I can't get your address to click into an email mode.
