In "playing" with my Peak Research code reader, to show the wife how to
use it, it came up with the Code for a large Evap Leak - this is for
when the gas cap is not tight, etc.
Problem is, I thought this would set the Check Engine light - it did
once before when the gas cap was actually loose. Now cap is fine, no
check engine light, yet the code keeps hanging in there.
Any idea? Have I actually got a problem, such as bad pressure sensor,
or is it nothing to worry about unless CEL comes on.
