I noticed that my 7 smokes at start up pr after sitting 8 hours. Smoke goes away pretty quick and runs good.. No smoke while driving or anything..

Also has a little miss when first cranked then smooths out nicley.. Again this is only on a cold start up. Turn key on, pumps runs tap gas twice and cranks on the second turn...

Anything I should look for? Or is this a normal thing... I love these cars more and more every day...
