I'd suspect "knock-back" of the pads by the discs, because of movement in the stub axles when you trounce round corners. I'm thinking of fitting the spacer system between the wheel bearings to avoid this. On the other hand, might be something completely different?

Excellent Mikey. It was worth all the heartache and head-scratching! :D

The spacers are a worthwhile mod in any case. I used the same kit.

Cheers, just bought a set. Must admit I fitted the bigger stubs a while back when I did the vented front disk conversion but its always been a problem.

Performance is fantastic, cruises easily over three figures. At this rate I’ll be banned within a month. :arrow:

Anyways I have an annoying but strong misfire at low revs. Gets worse over the duration of the 60m trip to work. Hence why I need to drive faster. :roll:

Seriously any ideas. Do coil packs break down like that? Only to recover when cold?

Coil packs (as in just the coils themselves), not necessarily but you have COP units IIRC with it being the later V6? Could be - initial failure mode is to fail only when hot, and then fail completely..

Lazy LPG solenoid perhaps?

Misfire at low revs might be a problem with the spark plugs/gaps?

Following-on from Phil's point, do you know the history/source of your "coil pack(s)"? I vaguely remember my nephew with a 4-cylinder Vauxhall (which had a large single lump stuck on top of the plugs) having problems with non-genuine OEM ones (aka "cheap") which only lasted a short while and failed when hot??

I had a similarly irritating misfire in another vehicle which, having swapped loads off things, turned out to be a dodgy spark plug. Another pal/scimitar owner on here found a similar misfire was a dodgy king lead between coil and dizzy.

thank you. the coil packs on the 3.2 are integral per cylinder bank. Three in a row and joined up into one piece, that you push in to all three spark plug housings.

They are genuine oem (bosch), but that might be the problem as they are probably as old as the engine, 10 years plus.

The first instance of misfire was not during the few local drives i did initially but after the first long drive (towards the end of 180 miles) . I've done about 400 miles now and it start earlier and earlier into a journey.

The challenge is, I have 4 of them and they are sided, so i have two of each bank type but there is a design fault and they trap water and this gets into them. so whilst the aftermarket ones are cr*p. (phil has also verified this) getting hold of old decent ones is bit of a lottery.

plugs are brand new but ill pop them out when i can face going into the garage again.

it has rained so hard today , on top of the previous 8 weeks, The garage i rent is very very damp. the dehumidifier simply cant cope : all the tools , spares etc are covered in moisture . Water is dripping from the roof everywhere and the spares are rusting as, god knows how, water is collecting in all the plastic trays that they live in. I took out a spare essex sump from storage and it had 1cm of water and was rusting from the inside !!!! Still, as someone on tv said today, it is only water which is a fair point.

I thought the coil packs are sided unless you turn them 180 degrees? I may be confusing this with the cam covers which have “1. 3. 5” on one edge and “2. 4. 6” upside down on the other edge?

Are you still running dual Lambda sensors and any indication from that?

I’ve no idea sadly what the Canems ECU might tell you (or not) in terms of fault diagnostics. Do you still have petrol capability and does it only do it on gas?
