your looking for deviation in values 2 and 4 in measured block 32, you should then do a round of G17, (or if it is really bad G17 at 400% of normal concentration) and re measure block 32, if that does not work additional work is required (but I have not looked into that yet).

Rep Gr 24, is repair group 24, it is detailed instructions on how to disassemble the whole intake area of the engine, I assume to diagnose a fault, if there is any specific section you are looking for let me know.

what are the descriptions for values 2 and 4 in measured block 32?
what parameter/variable, ie, timing? air flow? ???
what units and acceptable/in-range values?

Sorry, but I can't find that info I guess I would need VAS and the guided fault finding, to get that !

thanks, that is helpful
block 32
zone 4 (V8, 2 is for the V6)
the value (whatever it is) must have a deviation <15%
if >15% use 4 times as much

maybe it's the injector pulse width/on time?
if some are on longer (>15% more) than others they are occluded/plugged up???

hmmmmm

Guys, I emptied a bottle of Wynn's Formula Gold Petrol Treatment into half a tank of V-Power and drove the car in a thoroughly spirited manner. The exhaust was fairly smokey at times so something was definitely being burnt off. Driving the car hard ensured that I used up the fuel in the tank quickly and i've just filled up with a full tank of V-Power and the car runs noticeably smoother now, particularly on a cold start. It seems less lethargic and is running quieter now.

I use Redex injector cleaner on every other fill up. The amount of cr@p which came out of the exhaust the first time I used this was amazing and in the rear view mirror it was like I was driving a diesel.

The exhaust note is noticably different when using this also - a lot more popping and spitting noises and throttle blipped down shifts give a Group B rally car style bang.
