I do that all the time. Bring UK registered cars back from France that have been there for years so have no MoT or tax and take the most direct route from Dover ferry port to my tame MoT testing station. That fact that I usually come over on a Sunday when he isn't open and have to drive straight past my house to get there, means I have a stop off on the way to the test on the Monday morning. There's so few police on the roads these days that the chances of getting stopped are pretty remote anyway. As long as I've added the car to my insurance policy so it doesn't ping up as uninsured on ANPR the chances of getting stopped are even less.

It's even more fun in something that has just been imported from the US so doesn't have any plates on it at all. Done that quite a few times and never been stopped in one of those either.

But, but, but, it's not on gas..... Smell of petrol on the oil filler is probably because it's been started from cold and then switched off again lots of times. It isn't likely to be going anywhere with no MoT.

If the pressure drops and it switches back to petrol when you boot it, it isn't getting enough gas. Could be a clogged filter, clogged solenoid or the pipe has been squashed flat under the car somewhere.

Moisture out of the tank... that's a new one for me.

For lots of other people too. I've seen reference to it (and done it) but can't seem to find it in RAVE. It involves removing a plug at one end of the tank but as it is full of compressed air, the system needs to be depressurised first.

I've used these on mine http://www.island-4x4.co.uk/ignition-lead-4046-9498-hls102xp-p-889.html so a set of the Thor ones like this http://www.island-4x4.co.uk/ignition-lead-4046-9802-hls103xp-p-461.html should be fine. A lot cheaper than Magnecors too.

I very much doubt a burnt valve but if swapping the rails didn't cause the problem to move, it sounds like an electrical problem. Two possibles spring to mind, the LPG injector circuit for the one injector has failed so instead of pulsing it just opens the injector and leaves it open, or you have a short on the injector cut (where the LPG system intercepts the pulse to the petrol injector) and it isn't shutting off the petrol injector so the one cylinder is dual fuelling. Do you have the software for the system so you can switch the offending cylinder back to LPG? If you do, set it so all cylinders are running on LPG and, while running, clamp the hose from the LPG injector to the manifold. If it carries on running normally, it is dual fuelling (so with the LPG feed clamped off it is still running on petrol), if that one cylinder stops firing then the injector is being told to bung much more gas in than it should by the controller.

Usually yes but not all. On a multipoint reducer it is often a screw in the centre of where the diaphragm would be.

The problem with this install would seem to be that the pressure is too high and needs to be reduced but the timings are about right (1.2-15x petrol injection times). If the pressure is reduced then the timings will need to increase to get the quantity of gas injected correct so it is likely that the injector nozzles are too small.

Only US spec P38s had downstream sensors, rest of world only have the two upstream ones. The Yanks worry if the cats aren't doing their job, we don't give a ......

At least he's in the right place if it does catch fire........

I'd start to suspect the crank sensor too. Although you've not been near it, I assume you've disturbed, if not disconnected, the wiring to it. As the crank sensor can't give a fault code it does often come up with a cam sensor code instead as the two aren't in sync.

I took a car in for MoT that was fitted with winter tyres all year round and while it didn't fail the tester did put them on advise and suggested that they were changed. They were not pretty, the softer rubber compound looked like someone had been chewing on them as they didn't like the higher temperatures. That's why in regions where they get lots of bad weather everyone has two sets of wheels, a set with summer or all season tyres (all season in somewhere like the UK rather than somewhere that gets lots of very cold weather and snow) and a separate set with winter tyres.

Rimmers list it as in stock. If you order form them it will be with you tomorrow morning. They may be more expensive than the others but I've used them whenever I need something urgently because their next day delivery really is next day.

If it's M12 it will be one of the bolts that hold the caliper carrier to the hub not the smaller M8 that hold the caliper to the carrier. Not quite so easy to find as it's a fine thread too.

It's an alternator and mounting block off job to get to the cam sensor plug but I suspect you've either knocked the cable or trapped it between the block and head. Not too much of a problem if you have, just chop the wires off and piece them out.

It's the profile that dictates how they ride. My local Indie told me that you want 16s for comfort and 18s for looks and now owning cars with both I can see exactly what he means. The SE and Ascot, both on 18" wheels, give a noticeably harsher ride than mine on 16". I once drove a Range Rover Sport on 22" wheels and tyres resembling rubber bands, that was evil, you could feel every little ripple in the road.

yes slower acceleration and higher top speed! haha.

Errm no. Because the larger wheels have lower profile tyres so the rolling circumference stays the same. No different to 16" wheels having 65 profile tyres and 18" having 55 so the rolling circumference, and hence the overall gearing, doesn't change

Not connected the air flow sensor? I've forgotten that a couple of times, they don't like it much. Or an intake air leak? Try spraying around the place with brake cleaner. If the idle goes up, you've found the air leak. Favourite is the pipe to the fuel pressure regulator or the breather on the RH bank.

Can't be bad. Driven it yet?

That's nothing to worry about, the wheels are damn thick in that area. Bolts are standard M8 so you should be able to find one anywhere.

Try publishing the video so we can see it......
