Ok been down to Doncaster this morning to see J. DAVIES and discovered something that has us both a bit puzzeled, namely............................ why has a 5 cylinder engine only got a 4 injector gas system fitted ???? It is the factory fit option. Now as it is the centre cylinder that is missing its injector, I was wondering if the ecu switches to run as a 4 cylinder when on gas............ only thing I can think off !

It just doesn't look right, that and the right that there is no port for an injector there either just looks odd

Mine is on LPG, and mine has 5 injectors! Image What does it run like on 4 injectors?

I use to work as an lpg converter and no its not right a 4 cyl needs 4 a 5 needs 5 etc as pic above the only time you would have 1 injector would be on an intake system where it goes on before the maf but they where old systems and not very good . Has it the type of rail like above ?

Runs sound, just seems a bit misfiery on tick over.The inlet manifold is the one that is 'drilled' for the injectors and it doesn't look like yours, just a standard manifold with housings on the side......................unless the centre one is fitted from underneath !!?? I will try get some pics tomorrow if I can.

It has the factory fitted LPG option not an aftermarket one. There is no provision for an injector on cylinder 3 at the inlet manifold where the others have there's.

I should have taken a photo to put on here. Searching Google brings up this image where you can see no feed to cylinder 3 http://online-auction.s3.amazonaws.com/00218538_0001_800_02857753_218538_1.jpg

Yep, even with my bad 60 year old eyes, that looks the same.

Solved it LoL. After prodding my fingers through the gap, and burning them ( yes, this Dumbo did it after going for new plugs !!!) I FOUND THE OTHER FEED :saythat: It is fed upwards from the back of the distribution thing hence not being able to see it.
