Please Help!!!
Hi everyone
Hoping for some advice. I have a 993 c2 pre-v with 79,000 miles. I have had the car for 6 months covered 8,000 miles and it has been pretty reliable. Just recently it has developed a problem. If you start the car from cold it runs okay, however, if you switch the engine off after a run leave it for say 30 minutes then restart the car it stuggles to start seems to be firing on less than 6 cylinders, rocks from side to side and produces a very strong smell of petrol externally. As you drive away the problem clears itself but reappears if the temperature guage rises to above 9 o/c. The wiring harness,distributor caps,rotors and dme have all been replaced previous to this fault occurring. My local porsche independent connected the car to their tester and diagnosed a faulty o2 sensor which has been replaced but the problem is still apparent. Any ideas?
Many thanks

hey james
you got some good replies on the 993 forum .
expect many on here also , especially tommorrow when people are "working"
dme relay sounds good , as does a rubber hose (maybe vacuum) that starts to leak once the heat expands things .
NOTE : YOU SAY YOU SMELL PETROL .............. HAVE YOU CHECKED FOR LEAKS ??? !!!
might be stating the obvious , but the consequencies could be disasterous !!

Did the independent check the car after changing the O2 sensor? Could be a duff new sensor or a problem with wiring to/from the sensor rather than the sensor itself?
