I am not running a catch can yet but that is my next purchase. I haven’t replaced the solenoid but I have taken it out and checked the o-ring and tested it with 24 volts. Seemed to be okay I could hear the clicking. I’ve sprayed throttle body cleaner on all the PVC lines and did the smoke test and didn’t get any smoke out of the the lines.

Took the throttle body off last night again to check the O ring and all looks fine there. That was the only other thing I could think of.

IAT’s were way high because I didn’t purge the air out of the system so the intercooler pump went in the fail safe mode. But I have since purged that since the log and all seems good to go.

I have noticed when I run the system check in the scanner on hp tuners it’s saying the Evp system is not ready. Read that it should go back to ready if you take the car out and drive it some but it still has not went to ready.
