so to recap, it ran ok to start with so you put a new coil on and it random misfired? You then put the old coil back and changed the plugs and it now misfire at high revs?
If so its now pointing to a problem with the plugs or you disturbed something with the ignition leads when changing plugs/coil. I would go back to the old plugs and have a close check of the leads and dizzy cap.....

It's almost too late to save the great European alliance but when people say 'Europe wants to' they often don't realise that we as equal members hold a veto. We do/did on everything. That means 'we want to' as we've supported it through the people we've elected to be there. Each country rightly and property pays for their own implementation.
It too late for debate but that's the reality. Europe wasn't a seperate entity, we were Europe.
well I think I might have been another victim of false news as I cant find any mention anywhere of plans for the UK to have centralised, government operated MOT testing stations so I take my rant back🤐

I suppose you have to ask yourself Bob how much hassle in the past has normal brake fluid been in terms of bleeding the brakes and paint damage from leaks/spills....
-
Yes luckily my Vit won't start from cold without choke even in summer so I can spin it for as long as I like👍
-
Still worth checking them isn't it? If they do loosen off it doesn't help keep these boxes dry.....
-
I'd also add checking the tightness of all the gearbox bolts as mine always seem to be loose. I should probably replace all the spring washers to stop this happening....
-
No I find that tends to lift the car off the axle stands so with the wheel off the ground I just get the screwdriver between the wishbone and fixing bracket to lever the wishbone around to see if it's excessively easy to move.
-
Ok but I take it if you get battery voltage while running it's got to be a non ballasted system?
-
If the coil -ve doesn't show 0 you've then got to close the points or short it to ground which is why I suggested measuring running. Is there a problem doing it like that?
-
As a definitive answer to whether you have a ballast system or not you need to measure the voltage at the positive terminal of the coil with the engine running. Anything under 12v indicates a ballast system which needs a coil with a resistance of around 1.5 ohms. The resistor reduces the supply voltage to the coil after starting so a 3 ohm type would give a weak spark

Lift the MC rubber cover, could be leaking there so an easy repair.....
-
Fraid that fluid must have gone somewhere Paula. It's either along the master cylinder operator rod under the rubber cover and down the hole into the carpet or along the slave cylinder rod into the bell housing☹️
-
Iain perhaps they've changed the spec because the one I find on the Penrite site for their Classic Light (mineral) 20/60 shows API SF....

Can you explain a bit more Iain as just saying something is kak isn't very convincing😳

The ball race bearing is the only locating point so a lot of wheel side thrust must be taken by the u/j and diff. The bearing is press fitted on to the shafts parallel section not the taper which is for the hub and I don't remember there being a shoulder for it to go up against either so I think it's just done by measurement. Best to look at excellent diagram in the free to download work shop manual.....
-
I look for side play in the trunnions by pulling on the wheel when off the ground (up and down not so important as my wheels are not often airborne when driving😩) and a large screwdriver to lever with for rubber bushes.
-
Surprised it spins ok as the ball bearing would have to be pretty shot for that much play. Could it just be loose in the trunnion housing? Dont know if you can buy complete half shaft assemblies already reconned....
-
hmmmm not convinced on the grease idea whereas WD40 dries off possibly leaving an insulating coating without collecting dirt.....
-
Most of my rubber bushes are original and look knackered but you only have use a lever, as any MOT tester should, to show there's no excessive play plus it drives great😊
-
What engines that Clive?
-
I think the axial play is going to be down to outer ball bearing wear so the shaft might be reusable. Wonder what it's like to turn?
-
The bushes usually come fitted in new shocks so I'd be surprised if they're originals however do wonder what state the shocks are in....
-
No disagreement that synthetics are better but if contaminated with carbon and fuel I think their advantage is seriously reduced. They come into their own in moderns with 20k between changes and it comes out looking the same as it went in.....

I really can't see the point of synthetic oils in our engines, apparently the average annual mileage of a classic is 900 and even if it does more the scheduled changes are much more frequent than moderns which is what synthetics are best for. Our old low tune engines contaminate the oil much more rapidly than a modern so a normal oil changed frequently is ideal.....

Gt6 mk3 misfire different now
in Engine
Posted
I took it the misfire was when driving in which case one test I always do is pull out the choke slightly when the engine does it. This is to discount the possibility thats its fuel related as weak mixture can cause symptoms similar to yours.....
