I have been down all day thinking about your problem whilst sorting a 72 series 3 V8. Up and running after 33 years, a Townley conversion used by the MOD at Shoebury ranges. Still glad to see a smile back and have another wee dram. Best wishes from the UK.

Well done Mike - glad it turned-out simple in the end. As the good man South of you says : There's old parts, new parts, and good parts.

[@robjcp]

Hang in there Mike, nice job on the diagnosis. Recently had the same problem with Champion plugs but no fault codes as running megasquirt / gems. Was misfiring and smelling of fuel. NGK fixed it.

[@BritannicaRestorations]

You had to look carefully at the plug tester to see when it missed a beat or two

[@mattryan9427]

I feel your pain. I have a 99 disco 2 Bosch 4.0 automatic. Engine light came on code was cylinder 7 misfire. Bla bla bla. Replaced the plug same code came up. Replaced the wire , code came up again. Coil packs are original. So I looking at the motor trying to figure out how to replace the packs. Lucky for me I live in the desert, and my disco is pretty messy looking. So I took a cutting disk and cut a access hole in the firewall so I can remove the coil packs . It fixed the problem. I laughed when I saw this video, and thought I would share. Enjoy your videos.

[@BritannicaRestorations]

LoL! Years ago in my distant past, the S2a and 3 had the rear head core plugs leak - you are supposed to remove the head - but you could make a hole in the bulkhead and put a new one in! Lol!

Glad you got it sorted. It's the same with my car, the whole intake manifold has to come off to access the 3 plugs on the left bank. Designers don't go to the same meetings as the folk who have to service the things. Remember when changing a bulb was easy.

When I was a workshop supervisor at a Peugeot garage the service manager asked me to go to a local bodyshop where they had repaired a 405 but couldn't start it; it was a love job. I grabbed a set of plugs a tech. had just changed doing a service, cleaned and gapped them and fitted them on site. With the battery booster connected the car still wouldn't fire, nothing at all. We towed it to ours, fitted new (from the box) plugs and it fired up first time! How could plugs just taken from a car driven to us for service fail during replacement? I have no idea.

[@paulboon1100]

Why not work on these, you are an expert on them now!? (Lol) As I said a while ago, some things on Land Rovers are absolutely brilliant, others were designed and made by first year apprentices on Friday afternoon just before going to the pub, or maybe as a brain fart while at the pub for a few hours. I feel you. 😢

[@bimble7240]

Champion plugs used to be standard fit on almost all British stuff back in the 70's and 80's and they were never much good. I always fitted NGKs if I could get the right grade.

[@jamescaron6465]

It has come to my attention that the quality control on spark plugs isn’t what it used to be. When they say they come pre-gapped it doesn’t necessarily mean they were pré-gapped properly. Champion seem to be the worst defender of this now. I was told at standard flooded batteries are actually 25% lighter than they used to be 20 years ago. That means they have 25% less lead in them and it shows because I found that batteries don’t seem to last more than two or three years now for if you’re lucky. I recently switched over to AGM type batteries and that seem to have better luck with them. I know they’re more expensive, but if it comes down to paying some more money and getting stranded 40 miles from home I’ll take my chances with the extra money.

[@BritannicaRestorations]

I like AGM batteries. However, some a better than others 6 years ago I bought one of these for my Defender www.odysseybattery.com/products/odx-agm24-battery/ Was expensive. Lasted 12 months and would not charge They sent me another, but that only has half the power now - but good enough for my Perkins in the fork lift May get another AGM, but not an Odyssey

[@mpfour4203]

Always use original Denso or NGK , and check the gap yourself. Don’t take someone else’s word

[@greebo7857]

Those plugs could be knock offs, Mike. See a lot of that here.

[@SiCrewe]

Heh, I was going to say it's got to be the injector OR the plug but I didn't think the ECU could detect a plug-related issue that might be causing emissions problems. I mean, the ECU knows how long each injector is open so it knows if too much fuel is going in and causing an emissions fault. If the plug isn't firing properly, though, all the ECU knows (from the sensors in the exhaust) is that unburned fuel IS getting into the cat'. It doesn't necessarily know which cylinder is responsible for causing it. I guess the ECU is just detecting the misfire and ASSUMES that'll be causing unburned fuel to get sent into the cat' so it flags up the emissions fault. If the fault was simply "Misfire on Cylinder 2" (without all the emissions malarkey) you'd immediately assume it was the plug and check it without worrying about the injector. Also, I keep saying it but Land Rover didn't do themselves any favours by cramming V8s into every vehicle they sold in North America. If they'd sent TD5s over there, and convinced people to buy them instead of trucks with a V8 in, things might have been very different today.

[@BritannicaRestorations]

Don't forget these engines have knock sensors on the sides of each bank - they listen to the firing of each cylinder - if they detect a misfire that is out of range, it will throw a code Clever stuff - but also these sensors are responsible for detecting 'rough road running' and one of the causes of the 3 Amigos coming on the dash Now one would have thought that 'rough roads' were part and parcel of the LR world, but no - it deactivates the traction control, which is maybe why they went back to a manual diff lock in later vehicles

[@GavinEarnshaw]

The Bosch 'Thor' system can also detect an iffy combustion via the difference in acceleration of the flywheel on a power stroke. Couple that with knock sensors and the system can be too clever for its own good 😀

[@SiCrewe]

@@GavinEarnshaw I wonder if it DOES do that, though, or whether the fault-code generator just automatically creates an Emissions code at the same time as a misfire code? Just seems needlessly convoluted to me. As I said, when I saw those code I immediately thought "It's gotta be a plug or an injector" but then all the stuff about Emissions makes me think it must have detected fuel in the cat', which makes me think it's an injector fault. Course, once a mechanic is familiar with how the Thor ECU "thinks", they're more likely to be able to correctly diagnose the problem. I had a similar thing, recently, with my wife's Mini. Dashboard lights for the ABS and stability control were on. Scanner revealed a bunch of signal faults in the ABS system, which made me worry that something expensive was wrong with the ABS system. Fortunately, I also noticed a code related to the MAF sensor which DID say "below expected voltage". Problem turned out to be.... a flat battery! Which the super-smart ECU didn't see fit to mention anywhere.

[@GavinEarnshaw]

@@SiCrewe I read up a lot about the Bosch system when it was launched but I don't remember if it automatically put a presumptive 2nd fault code on. I did get fed up with Lucarse 14cux and gems so built a Megasquirt 2. My son is a mechanic and as an apprentice only 3 of them were actually interested in understanding why it was wrong. The rest just did what the fault code said. A total lack of systems engineering and silo mentality all around. Like you said checking the basics first.

[@gordonwedman3179]

I don't think these cars are hard to work on. I bought a 2000 P38 because it had the rare factory winch mount and Warn winch. It didn't run right. Hawkeye Total said misfire on cylinder 7. Changed plug. No difference. Changed plug wire. No difference. At this point it has to be the coil pack or the injector. You have to remove the upper manifold to get at either so I replaced both. Problem fixed. I doubt it was the coil pack as they rarely fail and I believe if it does fail you will get a misfire on at least two cylinders. I am not a professional mechanic.🙂
