Hi all, my engine did headgasket, since the strage faults: 1) Evaporative Control System makes noise for 1minute after sratup in the mornig, then goes away.
2) Check engine light comes on. Check whows fault: "93" "Evaporative Control System level low...."
Is there a covvention between the two? what is the meaning of the second?

Thanks.

First, what year is the truck, do you have SAI and you need to find another scanner, cause that is not a D2 code.
