1999 986 hot start problem

Hello,

could someone help me with problem on my Boxster 1999 2.5l 45000km Europe verison?

1. if i could start hot engine maybe 1-60minutes after the drive, engine starts normal-fast, but engine rev goes at first to 1800rpm and then drop to 200-300rpm and then engine stopped. Sometimes i must restart 5 times, until engine drop only to 400rpm, then goes to 1200rpm-600rpm-1000rpm, then correct idle speed. Sometimes i must push to gas pedal.

I changed these on my car: new spark plugs, new MAF sensor (Bosch), new idle speed regulator, new thermostat, new air intake temperature sensor, new coolant temperature sensor, new fuel filter, new K&N air filter, new lambda sonde (im from Europe, so on my car are only 2 sensors, but i changed 1, which was bad). Also i checked fuel pressure, fuel pump rele, all is OK, zero mistake at diagnostic.

Thank you very much for your help and any ideas

Look a little further down in this forum. This topic was very recently discussed. Possibly fuel tank purge valve.
