Hi All,
Slight concern with my 1998 C2 996.
The Long term fuel trim of bank 2 is fine and remains around 0% but Bank 1 is around +4% at idle but increases with revs and load to around +11% at cruise.
If it was a vacuum or exhaust leak I would imagine this would be worse at idle but its not and If it was fuel pressure i assume it would impact both banks?
I've put in a bottle of Injector cleaner but too early to tell if its made any difference but are there other common 996 issues that may cause this problem ?.
Asking as I'm about to do a 500mile motorway trip and don't want to think its running lean....
