Does the V6 use a pin on the flywheel to trigger the crankshaft sensor ?

All i can find on the subject atm - Looks like it needs to be carefully installed.

Hi all.

It appears that you've all been busy on my behalf since my last post! Not sure why, but I've not had any notifications about your posts, so my apologies for not replying to any of them.

Anyway, saga update....

Got the car back from the Auto Electrician yesterday.
Car is starting and running way better than it ever has. Bags of power now, but still misfiring/faltering, and the same old flat-spot at 2,000rpm....ugh!😕
Easiest way of explaining things is to put up a photo of the invoice, which explains things pretty well. Kind of.



Auto Electrician thinks maybe tappet noise. Neither myself or garage hear anything untoward in that area. There is however an irregular but constant 'hollow' chattering that is just audible from the front of the engine, possibly belt/pulley related. Garage has suggested I temporarily remove the belt and see if noise persists. Looks easy enough in the manual. Special 'tool' required though...thinking a bolt stuck in the holes would suffice?

Considering my luck recently, and with this being Friday the 13th, the car will no doubt catch fire as I remove the V-belt! Not to worry though, I'll keep a gallon of petrol nearby just in case!

By the way, I've booked the car into the garage again next Wednesday to specifically have this misfire fixed. Had enough of guessing my next move. Stick it in and let them get to the bottom of it. Wife and I are away on holiday for a week. Hoping (but doubting!) that it will all be smelling of roses upon our return 👍

I hate it when new parts go wrong. It really confuses the issue.
Glad you are making progress though,

Hi, yeah, bit of a pain with failing 'new' parts. Is there no quality control these days?
Not sure if it can be called progress, but at least the car is starting again, so I'm right back to where I was when I first bought the car.
Wow...that kinda sucks!

Hi everybody.

Ok, so some good(ish) news. Got a call at 5:30pm last night from the garage who have been looking at my car. They have replaced the N/S Lambda probe. The old one was definitely goosed. Covered in that white 'lean burn' coating. Anyway, mechanic said over the phone that he believes this has cured all of my engine issues.

So I went down and found them just finishing up with the exhaust analyser. I observed that the 'hollow chattering' noise heard previously is gone. The engine also now idles rock steady without any visible shake. Great to see.

So took the car for a short test drive with the mechanic sitting beside me. He explained just before setting off, that there was still a slight issue with the car wanting to stall when pulling off from a standstill if insufficient revs were used (below around 1,500rpm). He thought this might sort itself out as everything adjusts to the new lambda probe.

The car accelerated away without any of the 'bucking' previously experienced. Very impressed with how smooth everything was. Finally V6 smooth it seemed.
The stalling issue he mentioned, I have to say, wasn't an issue for me. If I was gentle with the clutch, the car would pull away with idling revs without issue, as it would with my normal method of pedal control for standstill takeoffs. Happy chappy!

But....as I was trying to recreate this near stall condition, and gently accelerating to go up through the gears, it became apparent that the 2,000rpm shudder is still there, but at a much reduced intensity. It can't be felt while accelerating normally from a standstill and progressing up through the gears, but when making progress as gently as possible, it is clear that things are not 100%. The mechanic was really disappointed to experience this, as he hadn't experienced it during his previous test drive.

I have to say, I think I would probably be very happy to have the car to drive as it is, because it has never felt so smooth, but we both feel that this tiny fault between 1,900rpm and 2,300rpm needs sorting. If only because it is annoying not to have it perfect. So, the car has been left with him again.

Progress has definitely been made though. Not far away now. Once I get the car back, I can concentrate on fixing the odometer and getting to the bottom of the groaning steering wheel. Then, I reckon I will have a perfectly functioning 80 2.6E Saloon in Gomera Pearl that I can be truly proud of and look forward to driving as my daily ride. Expect a few photos to appear on here once this happens guys!

Thanks again,
Alan
(Hope you are feeling better Mike!)

That’s great that you’ve made such progress!

I would only remind you that the car is 26 years old, and getting rid of the last few nighters (bearing in mind I have not driven the car!) might be a push too far. The law of diminishing returns and all that...

I find a similar thing on a motorbike forum I’m on. Some people spend twice what the bike is worth to try and get it perfect, when in reality their bike is 20 years old and has done 30,000 miles on one small cylinder. It’s never going to be new, and they need to accept some slight noises or vibrations.

All imho obviously! ��

Seems like you are getting there. Have you checked your engine mounts? They can cause odd vibrations if they are on the way out. Just an idea.

Hi.

Yes, I know what you're saying. However, sometimes it's about more than the value of the car. When passion for the vehicle, and blind determination kick in, common sense goes out the window. I also run a 1992 Mercedes 500SL, and I've spent 3 times the value of the car to get it to the point that it's at now. However, I don't drink, don't smoke, don't gamble and don't visit houses of disrepute. All things considered, I reckon I'm still quids in following the path that I'm treading!
