......
ill just take a trip to visit semi-naked TB in his pants 

Waaaaaaaaaaaaaaaaay waaaaaaaaaaaaaaaaaaaaaay too much information!!!!! 

To quote Jimbob ...... where's the mind bleach? !!!!!!!!! 

Get me a gallon too please

I'm getting there 

You just now need your own £thousands TechII to diagnose faults from a single manufacturer ..... 

The tool is irrelevent, the method/logic is what I'm trying to get over

Something that is frequently lacking in the skills of many mechanics.

That's because they are taught to instantly diagnose the most expensive part as faulty. Well that's how TG does it when you ask him about a problem.

Evans Halsaw in MK will have a job for him

My colleague made me laugh this morning. Turned up to work with plumes of smoke coming from under the bonnet of his Volvo. Had been to a "specialist" on the way to work complaining about terminal sounding noises. They muttered about the engine being "knackered". (they did a head gasket on the same engine about 4 months ago, but still...)

5 seconds looking under the bonnet and it was obvious by what was left of the air con compressor clutch smouldering away what the problem was. Engine sounded perfectly sweet.

Always start with the basics. How many times have we chased an electrical fault without checking the fuse first?

The logic bit OK, but without the proper diagnostic gear most mortals aren't able to turn injectors off individually

There are other ways of doing it, aren't there

Bringing this back up again, as its still fubared! 

Its had brand new HT leads, tripple checked they are on the in the right order at the dis pack end. Brand new plugs in 2-4-6, known good ones in 1-3-5 (ran out of new plugs! Some fat admin nicked them  )

Its got a clear miss-fire, slight metallic noise at idle, but not always present. Hold revs at say 900, sounds ok, no bad sounds but has a miss-fire. Sounds like its missing on a single pot 

Dispac has been inspected and its in perfect condition, think it had a new one very early on in our ownership but forgotten 

Tech2 plugged in, drop 2,3,4,5,6 injections you can notice the change. Turning off/on injector one no change. So pot1 is not firing, yet its had new plug & new lead.

Its possible I could have nicked/knocked the connector for injector one, although unlikely. Even more unlikely is injector 1 has failed. 

There was a distinct smell of eggs as the cats warmed up, in fact it was very, very strong.


Running theory at the moment, is that it was missing on pot 1 for a week or two. MotherT did not notice & its shagged pot1 

Because I had had damaged injector one loom/unplugged some how, why the smell of eggs? 

Could well be terminal for our dog carrier 

[doz]

Smell of eggs may be pointing to an over rich mixture reaching the cat due to the misfire. If it was me I'd want to see a spark on one cyl. Now I know it's not ideal but you may have to pull the lead and using a spare plug ark it out on the engine. Don't do it for to long it may well cause the dis pack to cry wolf. If you have a spark your left with compression or fuel. As you've got the smelly eggs I'd say you've got fuel maybe to much. So I'd do the comp test on cylinder 1 and see what it reads. After that I'd be hoinkin (technical term) the inlet off and swapping the injectors around with another cylinder to see if the problem follows the injector around. The only reason I'd carry out the comp test before the fuel saga is it's a damn sight easier to do!!!!

[tunnie]

Yes that's the feeling here too, TB suggested swapping an injector & checking the wiring. Its possible I've nicked it, so need to visually inspect it.

The other thought was swapping 1 & 4 on the DIS pack, see if the fault moves to pot4 

[Kevin Wood]

What does the plug on pot 1 look like? Dry/wet? Black / clean?

Eggy smells suggests it's getting unburnt fuel in the cat, which may have shagged the cat if it's been driven regardless. I doubt it will be anything serious, but worth a compression check on pot 1.

Plug 1 was dry, but red in colour 

I'm popping back mid week with a compression tester. If no compression, well thats that. If it does have decent compression then Plenum off again to check injector loom.

Have we seen injectors fail? Usually bullet proof 

As there is eggy smell, suggests fuel is not an issue, which suggests injector is working? Leaves either compresson or ignition problem? 

Fatty said its same issue he had with goldie, compression, fuel, good spark, good HT lead/DIS. But no firing on that pot, we all know what happened to that 

[Kevin Wood]

..but if it was fuelling with no spark the plug would have been soaking wet.

I'd make sure there are pulses at the injector when cranking, and replace the injector to see if that helps. I have a load of spares here if you need a few.

That is a good point 

Assume the replacement has to be 3.0 as well? Think 3.2's run at higher pressure?

If you have some spare, that's great. Many thanks 

Could drive over, but guess they are small & easy to post?
