Any advice would be appreciated regarding my LPG kit.
I have fitted a rebuilt 4.6 engine into my 1994 LSE in place of a very poorly 4.2.
It has an LPG kit on it that works briliantly to a point. It idles perfectly and revs freely all the way to the red line when parked but under load if i "boot it", it won't rev past 4200rpm. Lower down the rev range it has plenty of torqueif i ease back and let the revs rise slowly it will rev to 4800rpm.
It runs perfectly on petrol using the standard 14CUX ecu from the 4.2.
I am thinking that it is probable the vapouriser isn't capable of delivering enough gas to run the 4.6 at full chat. Does this sound right or am i overlooking something daft?
It is a slightly vague question but can I just swap the vapouriser with a higher capasity one or is it more involved?
