99 986 Stalling when A/C cuts on

[Boyantonwl]

Hello,

So I've done a ton of work to my Boxster but now have a new problem. It started when I replaced the charcoal canister and fuel vent valve. Car would start up and run perfectly but if I shut it off after it was hot it would have problems starting. I took it to mechanic and they diagnosed an air leak and corrected. I went to pick it up and it was perfect, until I turned on the A/C, then it stalled out. It seems as though my problems began when I was trying to chase down the evap leak and replaced those items, could they be causing the new issue? Thanks for the help

My guess would be that a part you replaced is installed incorrectly.
Example: your fuel vent valve. My guess is that when the car was hot and you shut if off
The fuel vent valve allowed fuel vapors into the intake. Causing a to rich mixture for hot starting. Sorry to say but you may want to go back and double check all your work and any electrical connections.

Thanks, I will take it apart again and double check, also got a new fuel filler vent valve to see if it was part of the issue.
