P1399 & p0441
Pending codes on this now.. Ugh
I know the evap is when I prolly broke the connector and put tape on it.. So thoughts on p1399?

Or is one causing the other?
The "pending" misfire (1399) could be a result of the evap issue, if the ECU/PCM is expecting flow from the evap to the intake and adjusts for it but it is not there - well you start messing with the air/fuel ratio.....at some point if those are too far out of line you will get a misfire.
Again, just food for thought.
