I had some dirty gas I expect as all my gas injectors started dying around the same time. I have a VZ with factory LPG, and I had 3 injectors replaced, but was warned the other 3 are not great either. Whilst they are working, they are definitely a bit flaky on idle. Petrol idling is fine. I was charged $190 each for them - eek! I rang a place in Adelaide recently and can get a whole second hand set for $220 that were known to be working before their removal, but not having done this job before, wondered if there are any pitfalls to be aware of. In particular is there any requirement to have a computer to adjust any settings once a replacement injector set is installed?
First of all is be getting a licensed LPG installer/repairer to do the work... But in saying that it shouldn't be to hard I guess
