I agree. It becomes a guessing game without a code. I guess the only thing I can suggest at this point is to start by checking fuel pump pressure when the temps cause a problem. It could even be the temp sensor causing the problems. If it doesn't read right, it may be telling the computer to lean the fuel mixture because it thinks it's hot or make the mixture rich because it senses it's cold.
