Okay here's a tough one for me:

Situation: brand new reman engine (4.7L) with 1k miles. Very early on I threw code P0456 which is a evaporation emission system leak (very small). Engine idles a little rough from start, but after some throttle, it goes away. Today I threw code P0300 Random/Multiple Cylinder Missfire.

I have brand new spark plugs and coils and gaskets.

So a couple questions:
  1. Is the missfire related to the evap leak?
  2. Fix the leak, then it'll fix the missfire?
  3. If they are unrelated, what could be causing the missfire?
  4. Should I park the truck until it's fixed?
Thanks Guys
