Re: Weird Misfire-could it be the timiing chain?
If it runs OK when cold or when sat for a while at a fuel station but when hot it has problems it could be related to the LPG injectors and LPG flow. Have you had those checked ?
Does it also do the same when running on petrol ?

Re: Weird Misfire-could it be the timiing chain?
Are you running flashlube or alternating between petrol and lpg ?
I have heard of burnt pistons with lpg on the Xtrails which would cause problems on both fuels.
My Xtrail has done 185k and though the engine is down on power and has less fuel economy with a suspected stretched timing chain, there is no misfire or shaking as you describe.

Timing Chain does not "stretch" .....
The links wear over time and this makes the overall length of the chain longer, effectively "stretching" it. This slight length change makes the number of links between crank and cam sprockets less by a fraction which changes the timing angle of the cams and hence the timing to a point which the ECU cannot adjust for enough.
Once I find the post about it in the overseas forum I found a while ago where they mentioned it I will reference it on our forum.

Re:
Very interesting, I just jumped on here to report a very similar issue with my Diesel T31 TL 2008 model, I'm waiting on my OBD2 scanner to arrive in the post to get the codes, no engine lights or anything indicating something is wrong. I have replaced Boost sensor - and the car was fine for 5km's and the problem came back, and I cleaned the MAF sensor and the car was fine for 30km's, I have a new MAF sensor also coming and one of those provent catch can's with full hose kit to keep the oil off the MAF sensor.
Keep us posted on what you find and I'll do the same.

Re:
I got my OBD2 scanner today, no faults recorded, car was behaving until about 30km in again, and then started to stutter under load (going up hill in 4th at approx 80km/h).
Actually my scanner checked the ECU history and it never has skipped a beat - including cleared codes - this has to be most frustrating thing as when you have a code it's an easy fix because you know what you're looking for.
I'm actually thinking not timing chain but small boost leak somewhere, however there is no tell tell signs anywhere under the hood (oil splat).
