ugh...I was HOPING it was simply the purge valve and that it was also what was throwing the codes. We took the purge valve off and tried blowing through it. I was hoping I could meaning it was stuck open but no. So, I've looked around a bit and found a bit of dry rotting which may or may not be the reason for the codes but to be honest, I'm more concerned with the sluggish starting. Any thoughts where to go from here on the sluggish starting???
