I run a multivalve on MV6. Teilo said it wasn't the new (at the time) very high flow, but was a higher than standard flow.

Doesn't appear to go lean at full chat, and I'm sure if it did, I would have killed the car by now

Have you discussed your stalling problem with LD/KW ? Could that be multi valve related?

Briefly with Mr Wood.

I'm putting it down to just driving like a 100% idiot  , though don't understand why it doesn't flick back to petrol if the gas pickup sucks air.

I did wonder if it was something with ICV, but then it'd happen on petrol.

This is a recent problem, and only started happening since popping new tyres on (and new front pads).

Why would that make any difference? Oh, silly me.

Yes come on Kev keep up! 

Wonder if the Fuel is thrown forward and flow is cut, solenoid  is also affected under heavy braking and can't click over back to petrol?  ....  For instance? Sticking possibly?   Could hear it click on Omega gay...?

But gas pressure sensor is in evap, so as soon as that drops, it should switch back to petrol, irrespective of what solenoids/pickups/whatever are doing.

My guess - under heavy braking you're not going to be burning any (or much) fuel so the pressure will hold up regardless. Even if the vapouriser sucks air. Hoof it away and demand for fuel suddenly rockets. If there is air (vapour) in the line it won't keep up.

The problem I have is that I have never been able to provoke a stumble on LPG until the tank is empty, and, even then, it catches the low pressure so fast the engine doesn't falter.

I had an AC Stag fitted to my Omega elite 3ltr back in December last year! I have had no trouble whats so ever. The cost of filling up the 85ltr tank cost around £55 and that will do between 290-320 miles (mostly m/way) that being fitted by ProfessAutogas for £1100 sounds to me that some people are prepared to try and save themselves money by purchasing the kit and doing a DIY on the Omega, let the Experts fit the kit.

I stalls under braking, not when reapplying power. Takes the PAS with it

Trouble is, the so-called "Experts" are mostly incompitent.

AC Stag only describes the ECU

The issues we've experienced are minor and most likely relate to tuning. Personally, I wouldn't pay a "Professional" to install any LPG kit to may car because I've not seen a job worthy of the money (except for Entwood's)

For £1100 I doubt they removed the manifold before drilling it... 90% of the time this will be fine but I'm not willing to take the chance of swarf damaging my engine Equally... I fitted my kit myself a little over 2 years ago and, apart from the little hiccup as it changes gear at full chat, it's faultless. Yours could have exactly the same issue but be set to switch to petrol and hide it

At the end of the day, you do what you are happy with... I don't let many people work on my cars... Never have and am unlikely to at any time in the near future.

Except yer back is breaked, and you'll be pleaing with someone to service it

I'd be concerned at the setup on that... Mine's a 90L tank (72L useable capacity) and I can get 350-400miles on mostly motorway runs (and that's not hanging about either )

When I went to Italy last September I cruised at between 90 and 120mph for a couple of tankfulls of LPG and got 380 miles without running out totally

Errrr.... Yeah... That's why I put many and not anyone

Apparently you've been voted to do the handbrake as you have lots of experience

Ooh, i had a little titter then.    .  Also an expert on in car aroma.... Apparently.

I'm afraid I also have never been able to allow anyone to work on my cars in my absence,I've always managed to do most jobs large and small myself, and coincidentally 3 days ago I took delivery of a lpg front end kit for miggy by arrangement with LD from Teilo,(once more thanks LD ) which I'm going to be installing,I'll get immense satisfaction from doing this, I hope to get any expert knowledge and advice I need from the forum, I'll know it's done proper, and learn a great deal, it has always been about knowing its done right and not so much for cost cutting
