Car would start up and run perfectly but if I shut it off after it was hot it would have problems starting.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

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.
