| The injectors would have been removed from the rails for cleaning & refitted with new O rings I thought an O ring could have been incorrectly fitted but the workshop denied that was a possibility. We have JDM 300zxtt's in Australia (right hand drive) so #5 cylinder IS on the drivers side but I'm not a big fan of the dremel method either. Yes, oem injectors due to lack of funds Passenger side O2 was trying to cycle but looked to be struggling. Engine was at operating temp when datascan was used (80deg C) O2 observations were at 2500rpm whilst stationary Don't know O2 voltage on cold start. Coolant temps rose to operating temp in approx 5 mins. Haven't done any cruising at 55-70mph because the workshop is in a the middle of a heavily built up area The semi faulty temp sensor idea makes sense but that would definately run both banks rich. Thanks for your help Ash. I've already wasted my time on one 800km round trip, I can see that another trip may be in order. This time I'll take my wideband with me.
