Subject:      I-4 rough idle  question....

I have a rough idle  issue that I need some help on....
 
The motor is an 1800 I-4,CIS. 50 degree
new rotor, dist cap, leads. Plugs a month old. 
 
the idle is rough, tends to slowly increase then decrease.
air and vacuum lines look good. 
 
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 flashes again. Has improved since I replaced rotor, cap,
leads and put another  new plug in, but its still not as consistent as
#2&3. Previous to the new leads,  #1 cylinder was a bit erratic too. 
 
any suggestions as to why this is happening? I'd really like to clean
this up before I take the air and vacuum lines apart to chase down the
idle problem...
