LPG Discussion Forum

Finally, got the car back and tested it. What a lovely little car that is. Engine appears more powerful and fuel consumption is only 6.2 liters of lpg per 100km or 45.5 UK mpg. In no case did I expect the last one.
It used to use about 9 to 10 liters. Engine bay was hot as hell. Almost couldn't ...

I didn't catch any noise from that area, but then, I didn't look particularly hard.

I will have the car back in a few hours and tell more.

On our attempt to replace the pre-cat lambda sensor, the threads are problematic and the old one hadn't been fully screwed.

There's my source of air, driving fuel trims out whack.

More news tomorrow.

For sure things are as you describe, but I am thinking that 20% is too much.

In addition, if the problem was with the fuel pump, i would see ever higher fuel trims at high rpms high load. It would even stumble or pull weakly but it doesn't.

I certainly don't expect the lpg system to work right ...

A vacuum leak would be less pronounced at higher loads, but it is not. Ltft is almost flat.

I tried resetting by disconnecting the battery for hours, but nothing happened. It kept its memory intact. I have no tool to do that. Still, fuel trims are not stuck, as proven by replacing the MAP sensor ...

40cm would generally be considered too long, 30 is normally the limit, though the shorter the better.

My understanding is the post cat sensor should not effect the trims, it's only there to monitor the cat, and should as such throw a error if its detecting the cat isn't doing anything.

Is the 20 ...

Perhaps erase the code and see if it comes up again first?

What is it like at idle?
What is the code you got?

Hi all,

I am trying to sort a Peugeot 307 1.4 8 valve.

First of all, it had very high LTFT on gasoline. It was ~32. Surprising it didn't throw any errors. I replaced the MAP sensor. That brought it down to ~20. Much better but not there yet.
Going to have both lambdas replaced, but still wondering ...

Hi all,

title says it all.

Thanks for all answers!

Thanks people!

What do you think of this little gem here? http://www.lpgshop.co.uk/lpg-tomasetto-artic-240hp-reducer/

I like it because it has an additional filter and also has preheating. Preheating means that I will be able to switch sooner to lpg and not have to use the temp sensor that my ...

I just ran the car on petrol for a while. It seems to run fine. I guess that excludes intake leaks.

Since it is believed that the pressure sensor is the least likely, I am probably looking at a tired reducer.

What do I do with it? Open it up and clean it? Get a rebuild kit? Get a new one?

Thanks!

But if you read the section on page 37, the gas itself has a Sulphur content of around 10ppm, it is the Sulphur in the stenching agent that adds the rest. Why do you want to know? Ultra Low Sulphur Diesel has around 10ppm but standard diesel is roughly 500ppm.

Oh, I didn't see that, thanks!

I am ...

Yes. pressure sensor is perhaps the least likely.

Ok, then I need to check for vacuum leaks I guess.

Hmmm, it says that according to the EU standard, the max is 100mg/kg, or 100ppm.

It's rather high, isn't it?

Thanks a lot.

Hi all,

I have an egas sly system installed in a peugeot 107. The system has a pressure sensor for the gaseous phase side.

Lately, when trying to adjust the gas pressure on the vaporizer, I noticed that the pressure would jump around quite a bit more than it used to. Previously. if it was at 1250 ...

Hi all,

I want to ask what the sulfur content is in lpg used for cars. Are there any relevant EU or UK laws about it?

Thanks in advance!

Thank you very much

Hi all.

I would like to know what is the average longevity of a reducer, one from an electronic injection system. Is there a specific interval where it should overhauled/changed, or is it just used until broken?

The same about the pipework from the tank to the reducer. What is the longevity of ...

Hi all! Sorry, it has been a long time and I haven't posted any news.

I had the Prius converted with the egas system. It has been really fine for one and a half year now.
Oddly enough, it goes through 25% more lpg than petrol, exactly as much as the calorific difference per liter between the two :D ...
