Car has new rotor & cap, & timing seems correct. Car idles very rough when cold but runs fine once it's warm. The plugs look good but have not been replaced.
The problem seems to be getting worse, any obvious things to check?

You need to have the fuel pressures checked when cold...The warm up compensator will give the pressure of about .9 bar when cold I think.
