Hello & Welcome.

1st this is to check for fault codes, use the link in my sig for a how2.

Apart from that, airleak now gone?  car serviced well?  is this on lpg or petrol, or both?

Hello and welcome to the forum.

Are you seeing a lack of power on both petrol and LPG or just LPG?

I am thinking that, if the LPG system was calibrated with a huge air leak, it will need to be recalibrated now. If it doesn't run well on petrol I would say you have another problem somewhere, though.

If it's recently been converted and has run poorly since, I would take the car back to the garage who did the conversion and point out their error as a first step.

If that doesn't bear fruit there is plenty of LPG knowledge on here.

Thanks guys really quick replies, No Fault codes, it is doing it on both petrol and LPG ? the conversion was four years ago.

both multirams working properly?

[hacked offf]

Thanks TheBoy dont know, how will i test them? i know months ago there is a small black box at the bottom for the radator that has a vacum pipe that go's to the multi rams this was broken i have boged it up

Blip the throttle. Rear should kick in around 1000rpm front around 4000rpm

Ah, thats the vac reservoir for the multirams. Has it been poor since then?

[hacked offf]

Thanks , it was poor before i found the vac res pipe fitting was broke as i said before i thought i'd fixed it how will i know if thats the problem and if the multi rams are working ,would that account for the total loss of power it is driving like a old slow tractor.

will putting the small pipes on the plenum in the worng order affect the whole air problem?

hi guys Just done the paper clip test got theses results
No 33 X 3  EGR valve voltage low
No 57 X 3 idle air control voltage low
No 74 X 3 mass air flow sensor voltage high
No 129 X 3 EGR valve feedback voltage low
what is do you think is my best course action

[RobG]

Disconnect the MAF and try it. Other codes possibly relate to low battery

There are 2 plugs that into the big pipe from the air filter which one should i disconect?  and what will it do when it is disconected?

[hacked offf]

Just unpluged air mass meter just made it worse tried to drive it just no power HOW SLOW!
