Ok, i bow to your greater knowledge of engines.

It must be crap being a new car salesman eh?
Every car you sell, thousands per year, and the owners all bring em back moaning every day that they dont run as well when cold, and you simply cant do anything about it.

Why would a COLD engine run worse than a hot one exactly? Give me your reasoning behind it instead of telling me i am wrong and rolling your eyes at me. Afford me the same respect i afford you and Educate me...
