listees:
I have a rough idle  issue that I'll throw out for list consideration.
The motor is an 1800 I-4,CIS. 50 degree
new rotor, dist cap, leads and plugs.
the idle is rough and tends to slowly increase then decrease.
air and vacuum lines look good. 
Here's the item list wisdom may help me clean up before I take all the
air and vacuum lines off.
When the timing light is connected to #1 , there's a nice steady
flashing- every time the plug fires. Same for #2&3. 
#4 cylinder is erratic. flashes regularly, then cuts out for a second or
two , then back again. Has improved since I replaced rotor cap leads and
put a new plug in, but its still not as consistent as #2&3.
