Ok not knowing a lot about interpreting live data I've managed to graph the integrator values from last night after Daz rebuilt it.



I'm assuming the big dip is when it was switched to gas but should sensor 1 be flatlining at 154 as it is most of the time?

I don't know a lot about interpreting that data either but I would have expected bot Lambda readings to fluctuate somewhat :-/ :-/

I wonder how they're getting on with this one? I hope they can at least solve the petrol running.

Yup it's running fine on petrol now, I'm just trying to see if I can decipher anything useful from some engine data we recorded after Daz stripped and rebuilt the inlets & plenum.

I take it that means the muppet had created can air leak then?

Was the coolant feed to the Vaporiser correct?

Two pipes run from vaporiser, one to the coolant bridge, the other to the HBV. We didn't know which way they should connect to the vaporiser (does it matter) so left them alone assuming the LPG guy will be able to check them tomorrow but the vaporiser is getting hot.

That will be fine

This bloody gas man has swapped and changed his mind loads of times

The last time it went funny sounds like when Rob left the scuttle panel of and it rained heavy. Rob thought that water had got into the dispack. But I reckon it sounds more like the appauling wiring got wet.

Aye it is a bit of a rats maze.
The professional way the ecu is just rattling around in the scuttle doesn't inspire confidence either.

That is where mine is - on a custom GRP plate.

Scuttle drains - are they clear?

try Little St garage ,bolton was doing gas years ago ,might be best idea give it too someone who nows what their doing ,if need anything i,m in wigan.cheers deecee

Not just flopping about in the scuttle then, you amateur Mr Imber.
Yes the scuttle drain must be clear otherwise the gas ECU would be needing an aqualung.

I just can't believe these "Professionals" get away with it

TBH Rob I'm at a bit of a loss but I will say that it doesn't sound like it is purely the LPG causing the problem....... Still think it's HT related personally though :-/ :-/ :-/

We are now thinking its the flatline lambda,as it runs fine until it warms up then the idle gets erratic.Captain Zok compared data from mine and data from his and the lambda was the only difference,so Daz is going to give that a go so heres hoping :-/ :-/

Ohhh.... Hang on a minute! I didn't know that! (Might be I didn't read the posts properly in the middle of the night )

I've been sorting the Sister-in-Laws Passat and that had exactly the same problem... Running perfect when cold but missing when hot. Her Cats were completely breaked... I mean really bad, they were blowing the precious metal out of the tailpipes

Give the Cats a shake and see if they rattle!

But the Lambda sounds possible... Perhaps it's under/over fuelling one bank when closed loop :-? :-?

rather hope the cats are ok,just had exhaust replaced,2 middle and backbox 2 week ago,I did give cats a bang whilst up on ramps and no rattles.So hoping its the lambda as we have virtually changed half the bloody parts under the bonnet,failing that might spend the best 20p I will of spent in a while on a box of "Englands Glory"

Can't say for an Omega with its two lambdas, but when the lambda failed on my Senator, it was as though I had an elastic throttle cable. OK when cold, but when warm, a push of the accelerator wouldn't do anything to start with, the car then slowly caught up with what the accelerator pedal was doing, and then you'd be backing off the accelerator while the car was getting faster.  :-?  :-?

not like that though Andy,but Daz has tried allsorts apart from the lambdas and the live data recordings captain did show a flatline lambda intergrator,I hope this is it,we will find out on Weds when Daz comes up again

[Robski]

Well the lambda sensors have been changed and that did not resolve the issue,intergrator 1 is still flatlining at 154.We also changed plugs which  made no difference.So thats 3 dis packs,3 sets of leads,3 sets of plugs,3 ICVs and still got this issue,could it possibly be a fault within the ECU.I'm getting to the point where I feel like just getting rid of the bloody thing anybody else got any suggestions before me and omega part company

I'm at a loss TBH Rob

I don't even think seeing it would make a huge difference after Daz has given it his all and it's been checked by the LPG specialist :-/ :-/ :-/

Can you just confirm that it plays up on both fuels but is more noticeable on LPG? If so, it still points towards an ignition (HT) problem to me

Hi Paul can confirm it does play up on both fuels but is more noticeable on lpg
