LPG Gas Problems on D2 - brand new installatioin

You could try KLR Automotive (DieselGas Technologies) for an opinion before you take it back to Minchinbury. KLR are close by at Kingswood (Penrith).

They did the LPG install on my P38A and are also LR specialists.

What gas system is it? OMVL Dream XXI? Impco BRI? Landi Renzo? Prins VSI?

Car was idling roughly on gas and petrol. Car drove well on both and made good power. Driving home around Ingleburn the car started missing with part throttle at 80,90,100,110, 120km. Apart from that, car went well.

Next morning, had a quick look under bonnet and noticed 3 clamps which hold the gas lines onto the gas injectors weren't where they should be, an oversight on installation I guess.

Started car and let warm up for 5 minutes and drove off, car was nearly stalling and backfiring (running on petrol). Car was gutless on petrol, until it switched over to gas, then ok and made power. Idle was still rough on gas.

Drove to work, missing at highway speed was increasing.

Drove home this afternoon, car missing and backfiring on petrol, which I think has ruined my airflow meter. I had only replaced it a few weeks ago. It was giving the same symptoms as the previous meter which was damaged (pre lpg).

Kept driving home (total trip is about 90km), car is totally gutless/unresponsive and miss is massive.

Car has a brand new k&n filter which was on car prior to lpg and new platinum plugs 3k old. I have been given cheper NGK plugs (BKR6E) which I was going to install this weekend, also given a paper air filter.

So as it stands, the air flow meter is likely to be damaged as the result of the back fires - I got the vapour injection so there would be no backfires.

Rang Gas installer, he reckons it's a problem with injectors which pulse for the gas injectors as well. Funny how the car was running perfect and making good power prior to the gas conversion.

Looking for some ideas, fixes, experiences help etc.

What a pain, cost $5720 - Mr Howards gas rebate $2k. So as you can imagine I'm annoyed.

Thanks.

Hi, their I have the same problem on a 2000 D2 only installed last week . the car ran fine before the install, then the same thing as yours they even left parts of when they gave the car back. Now its back in their work shop and having the coils and leads replaced at a cost of $850.00.

Lucky it's $0.55 a litre or I would rip the whole system out of mine and curse the day i ever did that to my vehicle. Once you get the plug leads sorted, you'll start to get on going problems with your ECU system that will no doubt never be fixed properly. The D2 System and the LPG system don't like each other at all. The biggest issue is the installers. They only have a vaugue idea of what they are doing to a Land Rover and in particualr a D2. I just live with my coughing, stinking, gutless Disco becuase there is simply no point in going back to the installer!

Bruce Davis installs some type of gas injection system, he has it on two of his own vehicles, one of which is a Defender 90 that has to be seen to be believed. :burnrubber:

Give Davis Performance a call and have him check it, and try to talk him into a drive of one of his td5's with gas injection .. :twisted:
