Re: Random Misfire Cyl4

Running on LPG with a coolant temperature of 20 degrees C? Not surprised it is misfiring.

Re: MGZT v6 conversion, question for the experts

Leaky reducer diaphragm? If you pull the vacuum line from the reducer off from where it connects to the manifold and put the end in a cup of water, you'll likely see gas bubbling out of it.

I don't suppose it has anything to do with all the spammers and their posts that we keep deleting that is screwing up the databases?

Re: Intake hose lenght

Depends how far down the back of the block they have to run. 300mm between injector and inlet valve is normally regarded as the maximum but you don't have a lot of space there to get them much closer.

Re: LPG Juddering under light load, works fine on heavy

Certainly sounds like a duff battery or bad battery connection, once running the car runs off the alternator rather than the battery. HID and LPG system won't draw that much more power, so a decent standard battery should be fine.

Re: LPG Juddering under light load, works fine on heavy

Nope, stick with whatever Vauxhall recommended as standard, don't waste money on 'special' plugs. Although it's in a Corsa, you should be able to find info on that engine when fitted to an Astra or Vectra. Thermostat housing won't have moved although you might find you've got less space to work in a...

Re: LPG Juddering under light load, works fine on heavy

While you are under the bonnet, treat it to a set of sparks plugs. LPG needs a better spark than petrol so even if it doesn't cure the current problem, it'll prevent others further down the line.

Re: How often should I service LPG system?

In that case you'll have to use an OBD reader. Look at the long and short term fuel trims when running on petrol and again when running on LPG. They should be the same.

But they'd never catch on in the UK. Banning vehicles rather than simply using them as an extra income stream, whatever next?

Re: Omvl dream xxi

Not sure if the L322 is the same as the earlier P38 but they can suffer a flat battery due to RF interference keeping the body control module awake. You really need it to be looked at by an auto electrician who will be able to check current draw while pulling different fuses to isolate which circuit...

Re: Cutting out when on gas

Are you sure it's a ticking from an injector and not the sound of a arc from one of the coils? As you've had to get brutal with them it's possible that you've cracked one.

Re: Omvl dream xxi

Unless the LED on the switch is staying on it's pretty unlikely, might be worth pulling the LPG fuse and seeing if you still have a battery drain. Rather than find a fault it's far easier for a mechanic to blame something aftermarket.

Re: How often should I service LPG system?

Does the car have a trip meter? If it does a simple calibration check is to look at the mpg figure when running on petrol and when on LPG. If they read the same, the petrol ECU isn't having to do any correction for an out of tune LPG system. Changing the filters every couple of years should be enoug...

Re: 1989 BMW E32 730i help needed

Best wait until you get the car and see exactly what petrol system it has. In Italy, where many of the LPG systems come from, all components must come from the same manufacturer. Rather than each one going their own way and designing everything there's a lot of badge engineering. AEB manufacture the...

Re: 1989 BMW E32 730i help needed

If it's running Motronic, I would have expected it to have a lambda sensor although according to http://www.ecolambda.co.uk/main/bmw.htm it doesn't until 04/92. Maybe it isn't Motronic or maybe an early version that didn't use one. Not really a problem to add one though, it just needs a boss welding...

Re: 1989 BMW E32 730i help needed

Yes, it takes an input from the existing lambda sensor and adjusts the gas flow from that. So it is a mixer system that you will be familiar with but instead of the manual power valve between the vaporiser and mixer, it uses a stepper motor valve controlled by the ECU. Unless you intend running it d...

Re: 1989 BMW E32 730i help needed

You could just keep it simple and stick with technology that matches the age of the car (and your experience) and fit a single point system. Much cheaper than a multipoint, far simpler and will work just as well.

Re: Jeep WJ issues

You haven't bled all the air out of the reducer so it needs the cooling system to be that much hotter before it gets up to temperature.
