In the past the worst thing I could do was to Start and Move the Cold car then Park it.. The Plugs would be Fowled.. BAD.. and it would limp to life on the Next Start.. and MUST be warmed up and driven to get it to clear.. This Morning was about 28-30 Deg.. I started the Zed, and ran it for 30 Seconds.. it felt 'Lopy' but was not stumbling.. I took the other car to work.. I cam back at noon, and Started up the Zed.. expecting a Cold Stumbly Start.. It Started on the First Compression Stroke and jumped to life.. No Stumbles.. No Hesitation..
This tells me I might need to take ~5% more fuel out of the 10C and lower Cells..
