I have a 2006 astra 1.9cdti 150 sri with 56,000miles on it and got myself an opcom to check and reset a ecn code for the throttle actuator valve - thats a whole different story
Anyways while playing with all the opcom options I came across injector quantity deviation...
Battery 13.5 @ 849rpm
cylinder 1 was 0.27
cylinder 2 was 1.58
cylinder 3 was -1.35
cylinder 4 was -0.50
cylinder 5 was...only kidding
I have hunted high and low on t'internet for acceptable ranges, anyone know what they are and is the ones I have good or bad?
reason why i ask is the car is a bit sluggish and know the throttle body/actuator valve is an issue and want to make sure when i replace it i wont get any more agro, altho i cleaned the sludge off it the other month and put a new egr with a modded gasket plate (10mm hole) in which cured the no power below 2500rpm issue.
anyways any advice greatly appreciated.
