Default strange problem after sitting for 2 days w/cops

After not driving the car for two days, I go to turn it over and to my surprise chug chug chug... no firing, it attempts to start after a few more cranks... then after checking all connections and grounds befor another crank, it began to fire more and more until it ran on two cyl. then gradually evened out, fine on all four perfect idle .... compression is good, log is fine, and map is good. I'm starting to think I have a cold solder joint in my cop harness or I have that random starting in cold cop problem.... also I have no capacitor. What do you all think?? I'm going to redo my cops' harness soon

Check for soot on the plug ends where they connect to the COP?

I've been having a similar "starts up on 2 cylinders" feel the last week or so. What's surprising to me is that it doesn't do it in the morning (when it's coldest), but in the afternoon when I get in the car to head home (when it's much warmer out). It cranks fine, but it seems to run on 2 cylinders for about 20 seconds, then evens out and never gives me another problem. It's so consistent it's almost like the ASE ending is fixing it. I plan to check my cranking/fixed MAP/timing settings to see if that could be causing it. Seems worse after it sits for a few days over the weekend. And I do have the capacitor so I don't think that's the problem. I'll check my plugs over the weekend to see how they look.

tune your ASE's Fixed MAP value.

guide:
  1. Open your ASE table.
  2. Look at your Fixed MAP value.
  3. Determine if you're too rich or too lean during ASE
  4. Fix VE Table and/or Fixed MAP value

Example of too lean:
