993 running rich

Hi all.

My black beauty is running a bit rich. The injectors are opening for around 5ms instead of the recommended 2ms.

This is causing some of great popping out its arse, but is causing a fair amount of fuel smell to be dragged inside the cabin via the heater and front window demister.

I plan to take it back to Motion Automotive to get it sorted, but what would be causing this and am I looking for big $$$ to fix?

Thanks

Chris

O2 sensor. That would be my first port of call.

 

I'd be saying the same.

 

What oil are you using? your cat may be clogged and this has inturn effected a failed O2 sensor.

 

Let us know how you go! O2 sensor is cheap!
