Fuel smell
 

Hi everyone. I have an 86 944 na and every now and then it smells like gasoline, especially when it is semi cold or run fast. I have to admit that this is my first car with fuel injection but if it had a carbuerator i would suspect that it needed adjustment. I have put some of the fuel injector cleaner in the tank and the problem abated somewhat but it is still there two weeks on. Does anyone have any ideas? Thank you
