I know it sounds crazy, but once it's sunny outside and over 65 it will not start. It cranks and turns, but will not start. It has a new battery, new plugs, dist & rotor, and a new air box thermostat. I also just cleaned the AMM. No help. The check engine light isn't on, and once it cools off at night, it starts right up. I tried to check for codes, and when I checked on port 6, it was 1-1-1, but on port 2 it was blank - not even 1-1-1.

In the winter it would start right up, but sometimes I had to rev it for a minute to let it warm up or it would die. Now that I think about it, during the winter if I turned it off and wanted to start it less than a minute later, it would not start and I would have to let it sit for a few minutes. Weird? I brought to my Volvo guy and he said he had never heard of that kind of problem it started fine for him when I left it there for a week. Any ideas?
