landi wiring causing miss fire

[gilli-lpg]

hi to all,as you can guess im new to the lpg thing,but with rising fuel cost i have a feeling lpg is going to become a lot more popular than it already is, and in my opinion the only real alternative available to us common folk?
anyhow! if i could kindly ask any one with the know how about my lpg problem.
firstly my car is a rover 75 auto 2.5 v6 with a landi system fitted by e-gas of birmingham in 2006.
my problem is when i switch to gas i get a symptom as if its only firing on 5 cylinders.of course being a v6 it will happily run allday on 5. i have traced the problem to a wiring loom that comes from the first injector matrix,it looks like some one has had ago at it before as there is an inline fuse been added to the red wire, i have looked every where for wiring diagrams but to no avail .
when you jiggle the wiring the engine fluctuates in revs.
when i purchased the car i had the gas checked for any safety issues & all was ok.
if any one has any information regarding this fault it would be a massive help to me.
many thanks.

It could also be an ignition problem swap the coil pack and spark plug to another cylinder and see if the problem follows the parts to the other cylinders.

If it is anything like my V6 Mondeo, your wiring to the injectors may have failed. To give you an idea, only 2 of the 6 injector plugs are still original (the rest started breaking internally and were replaced).

well firstly thank you to every one who read my post & replied,heres an update on my landi problem.
i took the car to highly recommended lpg guy who has so far found a dodgy bank of failed injectors so i need an injector matrix,he is also going to check the ecu just in case it has been damaged.money money money,print me some money.lol
just praying the ecu is ok.

well it seems my prayers were not good enough.i got the call back from my lpg guru & it seems i have 3 injectors down & a duff ecu,pow smack down,yep that hurt.thats what you get when you buy a second hand pile of italian ******,does any one no where i can get a hold of some prehistoric landi renzo matrix injectors & an e-gas ecu for my rover 75 v6.i think the ecu is the type with a handle on the side were you wind it up.lol..looks like me and the bank manager need to be buddies again..

If you've got to replace injectors and the ECU you may find it would be almost as cheap to replace the complete front end with something else. At least then you'll have a brand new system, with a warranty and hopefully, more readily available spares when and if you need them.
